We present XRISM Resolve observations of the core of the hot, relaxed galaxy cluster Abell 2029 (A2029). We find that the line-of-sight bulk velocity of the intracluster medium (ICM) within the central 180 kpc is at rest with respect to the brightest cluster galaxy, with a 3σ upper limit of ∣v bulk∣ < 100 km s−1. We robustly measure the field-integrated ICM velocity dispersion to be σ v = 169 ± 10 km s−1, obtaining similar results for both single-temperature and two-temperature plasma models to account for the cluster cool core. This result, if ascribed to isotropic turbulence, implies a subsonic ICM with Mach number and a nonthermal pressure fraction of 2.6 ± 0.3%. The turbulent velocity is similar to what was measured in the core of the Perseus cluster by Hitomi, but here in a more massive cluster with an ICM temperature of 7 keV, the limit on the nonthermal pressure fraction is even more stringent. Our result is consistent with expectations from simulations of relaxed clusters, but it is on the low end of the predicted distribution, indicating that A2029 is an exceptionally relaxed cluster with no significant impacts from either a recent minor merger or active galactic nucleus activity., 12 Mar. 2025, 982, 1, L5, L5, Scientific journal - Refereed, Nature, Springer Science and Business Media LLC, The bulk motion of gas in the core of the Centaurus galaxy cluster, Marc Audard; Hisamitsu Awaki; Ralf Ballhausen; Aya Bamba; Ehud Behar; Rozenn Boissay-Malaquin; Laura Brenneman; Gregory V.

- Astronomy & Astrophysics, EDP Sciences, The SRG/eROSITA All-Sky Survey: Large-scale view of the Centaurus cluster, Angie Veronica; Thomas H. Reiprich; Florian Pacaud; Jeremy S. Sanders; Efrain Gattuzz; Michael C. H. Yeung; Esra Bulbul; Vittorio Ghirardini; Ang Liu; Caroline Mannes; Alexander Morelli; Naomi Ota, Context. The Centaurus cluster is one of the brightest and closest clusters. Previous comprehensive studies were done only in its brightest part (r < 30′), where the centers of the main substructures (Cen 30 and Cen 45) are located, and only a small fraction of the outskirts has been studied.
Aims. Through this work, we aim to characterize the intracluster medium (ICM) morphology and properties of the Centaurus cluster out to the radius within which the density is 200 times the critical density of the Universe at the redshift of the cluster, R200 (91′).
Methods. We utilized the combined five SRG/eROSITA All-Sky Survey data (eRASS:5) to perform X-ray imaging and spectral analyses in various directions out to large radii. We employed some image manipulation methods to enhance small- and large-scale features. Surface brightness profiles out to 2R200 were constructed to quantify the features. We acquired the gas temperature, metallicity, and normalization per area profiles out to R200. We compared our results with previous Centaurus studies, cluster outskirts measurements, and simulations. Comprehensive sky background analysis was done across the field of view in particular to assess the variation of the eROSITA Bubble emission that partially contaminates the field.
Results. The processed X-ray images show the known sloshing-induced structures in the core, such as the cool plume, cold fronts, and ram pressure-stripped gas. The spectra in the core (r ≤ 11 kpc) are better described with a two-temperature (2T) model than an isothermal model. With this 2T analysis, we measured a lower temperature from the cooler component (∼1.0 keV) and a higher metallicity (∼1.6 Z⊙), signifying an iron bias. In the intermediate radial range, the temperature peaks at ∼3.6 keV, and we observed prominent surface brightness and normalization per area excesses in the eastern sector (Cen 45 location). Temperature enhancements near the location of Cen 45 imply that the gas is shock-heated due to the interaction with Cen 30. We reveal that the eastern excess emission extends even further out, reaching R500. The peak excess of normalization is located at ∼23′ from the center (8′ behind the center of Cen 45) with a 45% and 7.7σ above the full azimuthal value. This might be the tail or ram pressure-stripped gas from Cen 45. There is a temperature decrease of a factor of about two to three from the peak to the outermost bin at R500 − R200. We find good agreement between the outer temperatures (r > R2500) with the temperature profile from simulations and the temperature fit from Suzaku cluster outskirts measurements. We detect significant surface brightness emission to the sky background level out to R200 with a 3.5σ, followed by 2.9σ at 1.1R200. The metallicity at R500 − R200 is low but within the ranges of other outskirts studies.
Conclusions. We present the first whole azimuth beyond ∼30′ measurement of the ICM morphology and properties of the Centaurus cluster, and increasing the probed volume by a factor of almost 30. While the cluster core is rich in features as a result of active galactic nucleus feedback and sloshing, the cluster outskirts temperature of Centaurus follows the temperature profile of clusters in simulations as well as the temperature fit from other cluster outskirts measurements., 11 Feb. 2025, 694, A168, A168, Scientific journal, 10.1051/0004-6361/202450277 - Refereed, Publications of the Astronomical Society of Japan, Oxford University Press (OUP), Overionized plasma in the supernova remnant Sagittarius A East anchored by XRISM observations, XRISM Collaboration; Marc Audard; Hisamitsu Awaki; Ralf Ballhausen; Aya Bamba; Ehud Behar; Rozenn Boissay-Malaquin; Laura Brenneman; Gregory V Brown; Lia Corrales; Elisa Costantini; Renata Cumbee; Maria Diaz-Trigo; Chris Done; Tadayasu Dotani; Ken Ebisawa; Megan Eckar; Dominique Ecker; Teruaki Enoto; Satoshi Eguchi; Yuichiro Ezoe; Adam Foster; Ryuichi Fujimoto; Yutaka Fujita; Yasushi Fukazawa; Kotaro Fukushima; Akihiro Furuzawa; Luigi Gallo; Javier A García; Liyi Gu; Matteo Guainazzi; Kouichi Hagino; Kenji Hamaguchi; Isamu Hatsukade; Katsuhiro Hayashi; Takayuki Hayashi; Natalie Hell; Edmund Hodges-Kluck; Ann Hornschemeier; Yuto Ichinohe; Manabu Ishida; Kumi Ishikawa; Yoshitaka Ishisaki; Jelle Kaastra; Timothy Kallman; Erin Kara; Satoru Katsuda; Yoshiaki Kanemaru; Richard Kelley; Caroline Kilbourne; Shunji Kitamoto; Shogo Kobayashi; Takayoshi Kohmura; Aya Kubota; Maurice Leutenegger; Michael Loewenstein; Yoshitomo Maeda; Maxim Markevitch; Hironori Matsumoto; Kyoko Matsushita; Dan McCammon; Brian McNamara; François Mernier; Eric D Miller; Jon M Miller; Ikuyuki Mitsuishi; Misaki Mizumoto; Tsunefumi Mizuno; Koji Mori; Koji Mukai; Hiroshi Murakami; Richard Mushotzky; Hiroshi Nakajima; Kazuhiro Nakazawa; Jan-Uwe Ness; Kumiko Nobukawa; Masayoshi Nobukawa; Hirofumi Noda; Hirokazu Odaka; Shoji Ogawa; Anna Ogorzalek; Takashi Okajima; Naomi Ota; Stephane Paltani; Robert Petre; Paul Plucinsky; Frederick Scott Porter; Katja Pottschmid; Kosuke Sato; Toshiki Sato; Makoto Sawada; Hiromi Seta; Megumi Shidatsu; Aurora Simionescu; Randall Smith; Hiromasa Suzuki; Andrew Szymkowiak; Hiromitsu Takahashi; Mai Takeo; Toru Tamagawa; Keisuke Tamura; Takaaki Tanaka; Atsushi Tanimoto; Makoto Tashiro; Yukikatsu Terada; Yuichi Terashima; Yohko Tsuboi; Masahiro Tsujimoto; Hiroshi Tsunemi; Takeshi G Tsuru; Hiroyuki Uchida; Nagomi Uchida; Yuusuke Uchida; Hideki Uchiyama; Yoshihiro Ueda; Shinichiro Uno; Jacco Vink; Shin Watanabe; Brian J Williams; Satoshi Yamada; Shinya Yamada; Hiroya Yamaguchi; Kazutaka Yamaoka; Noriko Yamasaki; Makoto Yamauchi; Shigeo Yamauchi; Tahir Yaqoob; Tomokage Yoneyama; Tessei Yoshida; Mihoko Yukita; Irina Zhuravleva; Q Daniel Wang; Yuki Amano; Kojiro Tanaka; Takuto Narita; Yuken Ohshiro; Anje Yoshimoto; Yuma Aoki; Mayura Balakrishnan, Abstract
Sagittarius A East is a supernova remnant with a unique surrounding environment, as it is located in the immediate vicinity of the supermassive black hole at the Galactic center, Sagittarius A$^{*}$. The X-ray emission of the remnant is suspected to show features of overionized plasma, which would require peculiar evolutionary paths. We report on the first observation of Sagittarius A East with the X-Ray Imaging and Spectroscopy Mission (XRISM). Equipped with a combination of a high-resolution microcalorimeter spectrometer and a large field-of-view CCD imager, we for the first time resolved the Fe xxv K-shell lines into fine structure lines and measured the forbidden-to-resonance intensity ratio to be $1.39 \pm 0.12$, which strongly suggests the presence of overionized plasma. We obtained a reliable constraint on the ionization temperature just before the transition into the overionization state, of $\gt\! 4\:$keV. The recombination timescale was constrained to be $\lt\! 8 \times 10^{11} \:$cm$^{-3}\:$s. The small velocity dispersion of $109 \pm 6\:$km$\:$s$^{-1}$ indicates a low Fe ion temperature $\lt\! 8\:$keV and a small expansion velocity $\lt\! 200\:$km$\:$s$^{-1}$. The high initial ionization temperature and small recombination timescale suggest that either rapid cooling of the plasma via adiabatic expansion from dense circumstellar material or intense photoionization by Sagittarius A$^{*}$ in the past may have triggered the overionization., 26 Dec. 2024, 77, 1, L1, L8, Scientific journal, 10.1093/pasj/psae111 - Refereed, The Astrophysical Journal Letters, American Astronomical Society, The XRISM/Resolve View of the Fe K Region of Cyg X-3, Marc Audard; Hisamitsu Awaki; Ralf Ballhausen; Aya Bamba; Ehud Behar; Rozenn Boissay-Malaquin; Laura Brenneman; Gregory V.

The X-ray binary system Cygnus X-3 (4U 2030+40, V1521 Cyg) is luminous but enigmatic owing to the high intervening absorption. High-resolution X-ray spectroscopy uniquely probes the dynamics of the photoionized gas in the system. In this Letter, we report on an observation of Cyg X-3 with the XRISM/Resolve spectrometer, which provides unprecedented spectral resolution and sensitivity in the 2–10 keV band. We detect multiple kinematic and ionization components in absorption and emission whose superposition leads to complex line profiles, including strong P Cygni profiles on resonance lines. The prominent Fe xxv Heα and Fe xxvi Lyα emission complexes are clearly resolved into their characteristic fine-structure transitions. Self-consistent photoionization modeling allows us to disentangle the absorption and emission components and measure the Doppler velocity of these components as a function of binary orbital phase. We find a significantly higher velocity amplitude for the emission lines than for the absorption lines. The absorption lines generally appear blueshifted by ∼−500–600 km s−1. We show that the wind decomposes naturally into a relatively smooth and large-scale component, perhaps associated with the background wind itself, plus a turbulent, denser structure located close to the compact object in its orbit., 11 Dec. 2024, 977, 2, L34, L34, Scientific journal, 10.3847/2041-8213/ad8ed0 - Refereed, Publications of the Astronomical Society of Japan, Discovery of a hyperluminous quasar at z = 1.62 with Eddington ratio >3 in the eFEDS field confirmed by KOOLS-IFU on Seimei Telescope, Yoshiki Toba; Keito Masu; Naomi Ota; Zhen-Kai Gao; Masatoshi Imanishi; Anri Yanagawa; Satoshi Yamada; Itsuki Dosaka; Takumi Kakimoto; Seira Kobayashi; Neiro Kurokawa; Aika Oki; Sorami Soga; Kohei Shibata; Sayaka Takeuchi; Yukana Tsujita; Tohru Nagao; Masayuki Tanaka; Yoshihiro Ueda; Wei-Hao Wang, 04 Dec. 2024, Scientific journal, 10.1093/pasj/psae078

We present an initial analysis of the X-Ray Imaging and Spectroscopy Mission (XRISM) first-light observation of the supernova remnant (SNR) N 132D in the Large Magellanic Cloud. The Resolve microcalorimeter has obtained the first high-resolution spectrum in the 1.6–10 keV band, which contains K-shell emission lines of Si, S, Ar, Ca, and Fe. We find that the Si and S lines are relatively narrow, with a broadening represented by a Gaussian-like velocity dispersion of $\sigma _v \sim 450$ km s$^{-1}$. However, the Fe He$\alpha$ lines are substantially broadened with $\sigma _v \sim 1670$ km s$^{-1}$. This broadening can be explained by a combination of the thermal Doppler effect due to the high ion temperature and the kinematic Doppler effect due to the SNR expansion. Assuming that the Fe He$\alpha$ emission originates predominantly from the supernova ejecta, we estimate the reverse shock velocity at the time when the bulk of the Fe ejecta were shock heated to be $-1000 \lesssim V_{\rm rs}$ (km s$^{-1}$) $\lesssim 3300$ (in the observer frame). We also find that Fe Ly$\alpha$ emission is redshifted with a bulk velocity of $\sim 890$ km s$^{-1}$, substantially larger than the radial velocity of the local interstellar medium surrounding N 132D. These results demonstrate that high-resolution X-ray spectroscopy is capable of providing constraints on the evolutionary stage, geometry, and velocity distribution of SNRs., 10 Oct. 2024, 76, 6, 1186, 1201, Scientific journal, 10.1093/pasj/psae080 - Refereed, The Astrophysical Journal Letters, American Astronomical Society, XRISM Spectroscopy of the Fe Kα Emission Line in the Seyfert Active Galactic Nucleus NGC 4151 Reveals the Disk, Broad-line Region, and Torus, Marc Audard; Hisamitsu Awaki; Ralf Ballhausen; Aya Bamba; Ehud Behar; Rozenn Boissay-Malaquin; Laura Brenneman; Gregory V.

We present an analysis of the first two XRISM/Resolve spectra of the well-known Seyfert-1.5 active galactic nucleus (AGN) in NGC 4151, obtained in 2023 December. Our work focuses on the nature of the narrow Fe K α emission line at 6.4 keV, the strongest and most common X-ray line observed in AGN. The total line is found to consist of three components. Even the narrowest component of the line is resolved with evident Fe K α,1 (6.404 keV) and K α,2 (6.391 keV) contributions in a 2:1 flux ratio, fully consistent with neutral gas with negligible bulk velocity. Subject to the limitations of our models, the narrowest and intermediate-width components are consistent with emission from optically thin gas, suggesting that they arise in a disk atmosphere and/or wind. Modeling the three line components in terms of Keplerian broadening, they are readily associated with (1) the inner wall of the “torus,” (2) the innermost optical “broad-line region” (or “X-ray BLR”), and (3) a region with a radius of r ≃ 100 GM/c 2 that may signal a warp in the accretion disk. Viable alternative explanations of the broadest component include a fast-wind component and/or scattering; however, we find evidence of variability in the narrow Fe K α line complex on timescales consistent with small radii. The best-fit models are statistically superior to simple Voigt functions, but when fit with Voigt profiles the time-averaged lines are consistent with a projected velocity broadening of FWHM . Overall, the resolution and sensitivity of XRISM show that the narrow Fe K line in AGN is an effective probe of all key parts of the accretion flow, as it is currently understood. We discuss the implications of these findings for our understanding of AGN accretion, future studies with XRISM, and X-ray-based black hole mass measurements., 01 Sep. 2024, 973, 1, L25, L25, Scientific journal, 10.3847/2041-8213/ad7397 - Not Refereed, Space Telescopes and Instrumentation 2024: Ultraviolet to Gamma Ray, SPIE, Development and operation status of X-Ray Imaging and Spectroscopy Mission (XRISM), Makoto S.

(AGNs) for approximately 1 million member galaxies of galaxy groups and
clusters, with 0.1 $<$ cluster redshift ($z_{\rm cl}$) $<$ 1.4, selected using
Subaru Hyper Suprime-Cam, the so-called CAMIRA clusters. In this research, we
focused on the AGN power fraction ($f_{\rm AGN}$), which is defined as the
proportion of the contribution of AGNs to the total infrared (IR) luminosity,
$L_{\rm IR}$ (AGN)/$L_{\rm IR}$, and examined how $f_{\rm AGN}$ depends on (i)
$z_{\rm cl}$ and (ii) the distance from the cluster center. We compiled
multiwavelength data using the ultraviolet--mid-IR range. Moreover, we
performed spectral energy distribution fits to determine $f_{\rm AGN}$ using
the CIGALE code with the SKIRTOR AGN model. We found that (i) the value of
$f_{\rm AGN}$ in the CAMIRA clusters is positively correlated with $z_{\rm
cl}$, with the correlation slope being steeper than that for field galaxies,
and (ii) $f_{\rm AGN}$ exhibits a high value at the cluster outskirts. These
results indicate that the emergence of AGN population depends on the redshift
and environment and that galaxy groups and clusters at high redshifts are
important in AGN evolution. Additionally, we demonstrated that cluster--cluster
mergers may enhance AGN activity at the outskirts of particularly massive
galaxy clusters. Our findings are consistent with a related study on the CAMIRA
clusters that was based on the AGN number fraction., 01 May 2024, Scientific journal, 10.3847/1538-4357/ad32c6 - Refereed, Astronomy & Astrophysics, EDP Sciences, The SRG/eROSITA all-sky survey, A.

Zhang; X. Zheng, The eROSITA telescope array aboard the Spektrum Roentgen Gamma (SRG) satellite began surveying the sky in December 2019, with the aim of producing all-sky X-ray source lists and sky maps of an unprecedented depth. Here we present catalogues of both point-like and extended sources using the data acquired in the first six months of survey operations (eRASS1; completed June 2020) over the half sky whose proprietary data rights lie with the German eROSITA Consortium. We describe the observation process, the data analysis pipelines, and the characteristics of the X-ray sources. With nearly 930 000 entries detected in the most sensitive 0.2–2.3 keV energy range, the eRASS1 main catalogue presented here increases the number of known X-ray sources in the published literature by more than 60%, and provides a comprehensive inventory of all classes of X-ray celestial objects, covering a wide range of physical processes. A smaller catalogue of 5466 sources detected in the less sensitive but harder 2.3–5 keV band is the result of the first true imaging survey of the entire sky above 2 keV. We present methods to identify and flag potential spurious sources in the catalogues, which we applied for this work, and we tested and validated the astrometric accuracy via cross-comparison with other X-ray and multi-wavelength catalogues. We show that the number counts of X-ray sources in eRASSl are consistent with those derived over narrower fields by past X-ray surveys of a similar depth, and we explore the number counts variation as a function of the location in the sky. Adopting a uniform all-sky flux limit (at 50% completeness) of F05–2 keV > 5 × 10−14 erg s−1 cm−2, we estimate that the eROSITA all-sky survey resolves into individual sources about 20% of the cosmic X-ray background in the 1–2 keV range. The catalogues presented here form part of the first data release (DR1) of the SRG/eROSITA all-sky survey. Beyond the X-ray catalogues, DR1 contains all detected and calibrated event files, source products (light curves and spectra), and all-sky maps. Illustrative examples of these are provided., 31 Jan. 2024, 682, A34, A34, Scientific journal, 10.1051/0004-6361/202347165

Miyazaki; J. S. Sanders, Context. We present the results of a systematic X-ray analysis of optically rich galaxy clusters detected by the Subaru Hyper Suprime-Cam (HSC) survey in the eROSITA Final Equatorial-Depth Survey (eFEDS) field.
Aims. Through a joint analysis of the SRG (Spectrum Roentgen Gamma)/eROSITA and Subaru/HSC surveys, we aim to investigate the dynamical status of the optically selected clusters and to derive the cluster scaling relations.
Methods. The sample consists of 43 optically selected galaxy clusters with a richness >40 in the redshift range of 0.16–0.89. We systematically analyzed the X-ray images and emission spectra using the eROSITA data. We identified the brightest cluster galaxy (BCG) using the optical and far-infrared databases. We evaluated the cluster’s dynamical status by measuring three quantities: offset between the X-ray peak and BCG position, the gas concentration parameter, and the number of galaxy-density peaks. We investigated the luminosity–temperature and mass–luminosity relations based on eROSITA X-ray spectra and HSC weak-lensing data analyses.
Results. Based on these three measurements, we estimated the fraction of relaxed clusters to be 2(< 39)%, which is smaller than that of the X-ray-selected cluster samples. After correcting for a selection bias due to the richness cut, we obtained a shallow L−T slope of 2.1 ± 0.5, which is consistent with the predictions of the self-similar model and the baseline model incorporating a mass–concentration relation. The L−M slope of 1.5 ± 0.3 is in agreement with the above-cited theoretical models as well as the data on the shear-selected clusters in the eFEDs field.
Conclusions. Our analysis of high-richness optical clusters yields a small fraction of relaxed clusters and a shallow slope for the luminosity–temperature relation. This suggests that the average X-ray properties of the optical clusters are likely to be different from those observed in the X-ray samples. Thus, the joint eROSITA and HSC observations are a powerful tool in extending the analysis to a larger sample and understanding the selection effect with a view to establish cluster scaling relations., 18 Jan. 2023, 669, A110, A110, Scientific journal, 10.1051/0004-6361/202244260 - Refereed, Publications of the Astronomical Society of Japan, Oxford University Press (OUP), Optical IFU observations of GOALS sample with KOOLS-IFU on Seimei Telescope: Initial results of nine U/LIRGs at z<0.04, Yoshiki Toba; Satoshi Yamada; Kazuya Matsubayashi; Koki Terao; Aoi Moriya; Yoshihiro Ueda; Kouji Ohta; Aoi Hashiguchi; Kazuharu G Himoto; Hideyuki Izumiura; Kazuma Joh; Nanako Kato; Shuhei Koyama; Hiroyuki Maehara; Rana Misato; Akatoki Noboriguchi; Shoji Ogawa; Naomi Ota; Mio Shibata; Nozomu Tamada; Anri Yanagawa; Naoki Yonekura; Tohru Nagao; Masayuki Akiyama; Masaru Kajisawa; Yoshiki Matsuoka, Abstract
We present ionized gas properties of nine local ultra/luminous infrared galaxies (U/LIRGs) at z < 0.04 through Integral Field Unit (IFU) observations with KOOLS-IFU on the Seimei Telescope. The observed targets are drawn from the Great Observatories All-sky LIRG Survey (GOALS), covering a wide range of merger stages. We successfully detect emission lines such as Hβ, [O iii]λ5007, Hα, [N ii]λλ6549, 6583, and [S ii]λλ6717, 6731 with a spectral resolution of R = 1500–2000, which provides (i) a spatially resolved (∼200–700 pc) moment map of ionized gas and (ii) diagnostics for an active galactic nucleus (AGN) within the central ∼3–11 kpc in diameter for our sample. We find that the [O iii] outflow that is expected to be driven by an AGN tends to be stronger (i) towards the galactic center and (ii) as a sequence of the merger stage. In particular, the outflow strength in the late-stage (stage D) mergers is about 1.5 times stronger than that in the early-state (stage B) mergers, which indicates that galaxy mergers could induce AGN-driven outflow and play an important role in the co-evolution of galaxies and supermassive black holes., 01 Dec. 2022, 74, 6, 1356, 1367, Scientific journal, 10.1093/pasj/psac073 - Refereed, Journal of Low Temperature Physics, Springer Science and Business Media LLC, Super DIOS Project for Exploring “Dark Baryon”, K.

- Refereed, Astronomy & Astrophysics, EDP Sciences, X-ray studies of the Abell 3158 galaxy cluster with eROSITA, B. Whelan; A. Veronica; F. Pacaud; T. H. Reiprich; E. Bulbul; M. E. Ramos-Ceja; J. S. Sanders; J. Aschersleben; J. Iljenkarevic; K. Migkas; M. Freyberg; K. Dennerl; M. Kara; A. Liu; V. Ghirardini; N. Ota, Context. The most nearby clusters are the best places for studying physical and enrichment effects in the faint cluster outskirts. The Abell 3158 cluster (A3158), located at z = 0.059, is quite extended with a characteristic radius r200 = 23.95 arcmin. The metal distribution in the outskirts of this cluster has previously been studied with XMM-Newton. In 2019, A3158 was observed as a calibration target in a pointed observation with the eROSITA telescope on board the Spektrum-Roentgen-Gamma mission. Bright large clusters, such as A3158, are ideal for studying the metal distribution in the cluster outskirts, along with the temperature profile and morphology. With the deeper observation time of the eROSITA telescope, these properties can now be studied in greater detail and at larger radii. Furthermore, bright nearby clusters are ideal X-ray instrumental cross-calibration targets as they cover a large fraction of the detector and do not vary in time.
Aims. We first compare the temperature, metal abundance, and normalisation profiles of the cluster from eROSITA with previous XMM-Newton and Chandra data. Following this calibration work, we investigate the temperature and metallicity of the cluster out to almost r200, measure the galaxy velocity dispersion, and determine the cluster mass. Furthermore, we search for infalling clumps and background clusters in the field.
Methods. We determined 1D temperature, abundance, and normalisation profiles from both eROSITA and XMM-Newton data as well as 2D maps of temperature and metal abundance distribution from eROSITA data. The velocity dispersion was determined and the cluster mass was calculated from the mass–velocity dispersion (M200−συ) relation. Galaxy density maps were created to enable a better understanding of the structure of the cluster and the outskirts.
Results. The overall (i.e. in the range 0.2−0.5r500) temperature was measured to be 5.158 ± 0.038 keV. The temperature, abundance, and normalisation profiles of eROSITA all agree to within a confidence level of about 10% with those we determined using XMM-Newton and Chandra data, and they are also consistent with the profiles published previously by the X-COP project. The cluster morphology and surface brightness profile of cluster Abell 3158 appear to be regular at a first glance. Clusters that have such profiles typically are relaxed and host cool cores. However, the temperature profile and map show that the cluster lacks a cool core, as was noted before. Instead, an off-centre cool clump lies to the west of the central cluster region, as reported previously. These are indications that the cluster may be undergoing some sloshing and merger activity. Furthermore, there is a bow-shaped edge near the location of the cool gas clump west of the cluster centre. Farther out west of the X-ray images of A3158, an extension of gas is detected. This larger-scale extension is described here for the first time. The gas metallicity (~0.2 solar) measured in the outskirts (»r500) is consistent with an early-enrichment scenario. The velocity dispersion of the cluster member galaxies is measured to be 1058 ± 41 kms−1 based on spectroscopic redshifts of 365 cluster member galaxies and the total mass is determined as M200,c = 1.38 ± 0.25 × 1015M⊙. The mass estimate based on the X-ray temperature is significantly lower at M200 = 6.20 ± 0.75 × 1014M⊙, providing further indications that merger activity boosts the velocity dispersion and/or biases the temperature low. An extended X-ray source located south of the field of view also coincides with a galaxy overdensity with spectroscopic redshifts in the range 0.05 < z < 0.07. This source further supports the idea that the cluster is undergoing merger activity. Another extended source located north of the field of view is detected in X-rays and coincides with an overdensity of galaxies with spectroscopic redshifts in the range of 0.070 < z < 0.077. This is likely a background cluster that is not directly related to A3158. Additionally, the known South Pole Telescope cluster SPT-CL J0342-5354 at z = 0. 53 was detected., Jul. 2022, 663, A171, A171, Scientific journal, 10.1051/0004-6361/202141621 - Refereed, Astronomy & Astrophysics, EDP Sciences, The eROSITA view of the Abell 3391/95 field: Case study from the Magneticum cosmological simulation, Veronica Biffi; Klaus Dolag; Thomas H. Reiprich; Angie Veronica; Miriam E. Ramos-Ceja; Esra Bulbul; Naomi Ota; Vittorio Ghirardini, Context.Clusters of galaxies reside at the nodes of the cosmic web, interconnected by filamentary structures that contain tenuous diffuse gas, especially in the warm-hot phase. Galaxy clusters grow by mergers of smaller objects and gas that are mainly accreted through these large-scale filaments. For the first time, the large-scale cosmic structure and a long gas-emission filament have been captured by eROSITA on board the Spectrum-Roentgen-Gamma mission in a direct X-ray observation of the A3391/95 field.
Aims.We investigate the assembly history of an A3391/95-like system of clusters and the thermo-chemical properties of the diffuse gas in it by connecting simulation predictions to the eROSITA observations with the aim to constrain the origin and nature of the gas in the pair-interconnecting bridge.
Methods.We analysed the properties of a system resembling A3391/95, extracted from the (352h−1cMpc)3volume of the Magneticum Pathfinder cosmological simulations atz= 0.07. We tracked the main progenitors of the pair clusters and of surrounding groups back in time to study the assembly history of the system and its evolution.
Results.Similarly to the observed A3391/95 system, the simulated cluster pair is embedded in a complex network of gas filaments, with structures aligned over more than 20 projected Mpc, and the whole region collapses towards the central overdense node. The spheres of influence (3 ×R200) of the two main clusters already overlap atz= 0.07, but their virial boundaries are still physically separated. The diffuse gas located in the interconnecting bridge closely reflects the warm-hot intergalactic medium, with a typical temperature of ~1 keV and an overdensityδ ~100 with respect to the mean baryon density of the Universe, and a lower enrichment level compared to the intra-cluster medium in clusters. We find that most of the bridge gas collapsed from directions roughly orthogonal to the intra-cluster gas accretion directions, and its origin is mostly unrelated to the two cluster progenitors. We find clear signatures in the surrounding groups of infall motion towards the pair, such as significant radial velocities and a slowdown of gas compared to dark matter. These findings further support the hypothesis that the Northern Clump (MCXC J0621.7-5242) cluster infalls along a cosmic gas filament towards Abell 3391 and might be merging with it.
Conclusions.We conclude that in this configuration, the pair clusters of the A3391/95-like system are in a pre-merger phase and have not yet interacted. The diffuse gas in the interconnecting bridge is mostly warm filament gas and not tidally stripped cluster gas., 18 May 2022, 661, A17, A17, Scientific journal, 10.1051/0004-6361/202141107 - Refereed, Astronomy & Astrophysics, EDP Sciences, The eROSITA Final Equatorial-Depth Survey (eFEDS), A.

optically-selected merging cluster, HSC J085024+001536, from the Subaru HSC-SSP
survey. Both the member galaxy density and the weak-lensing mass map show that
the cluster is composed of southeast and northwest components. The
two-dimensional weak-lensing analysis shows that the southeast component is the
main cluster, and the sub- and main-cluster mass ratio is
$0.32^{+0.75}_{-0.23}$. The northwest subcluster is offset by $\sim700$ kpc
from the main cluster center, and their relative line-of-sight velocity is
$\sim1300\,{\rm km s^{-1 } }$ from spectroscopic redshifts of member galaxies.
The X-ray emission is concentrated around the main cluster, while the gas mass
fraction within a sphere of $1'$ radius of the subcluster is only
$f_{\mathrm{gas } }=4.0^{+2.3}_{-3.3}\%$, indicating that the subcluster gas was
stripped by ram pressure. X-ray residual image shows three arc-like excess
patterns, of which two are symmetrically located at $\sim550$ kpc from the
X-ray morphological center, and the other is close to the X-ray core. The
excess close to the subcluster has a cold-front feature where dense-cold gas
and thin-hot gas contact. The two outer excesses are tangentially elongated
about $\sim 450-650$ kpc, suggesting that the cluster is merged with a non-zero
impact parameter. Overall features revealed by the multi-wavelength datasets
indicate that the cluster is at the second impact or later. Since the
optically-defined merger catalog is unbiased for merger boost of the
intracluster medium, X-ray follow-up observations will pave the way to
understand merger physics at various phases., 13 Jun. 2021, 73, 3, 584, 595, Scientific journal, 10.1093/pasj/psab022 - Refereed, Astronomy & Astrophysics, EDP Sciences, The Abell 3391/95 galaxy cluster system.

Context. Inferences about dark matter, dark energy, and the missing baryons all depend on the accuracy of our model of large-scale structure evolution. In particular, with cosmological simulations in our model of the Universe, we trace the growth of structure, and visualize the build-up of bigger structures from smaller ones and of gaseous filaments connecting galaxy clusters.Aims. Here we aim to reveal the complexity of the large-scale structure assembly process in great detail and on scales from tens of kiloparsecs up to more than 10 Mpc with new sensitive large-scale observations from the latest generation of instruments. We also aim to compare our findings with expectations from our cosmological model.Methods. We used dedicated SRG/eROSITA performance verification (PV) X-ray, ASKAP/EMU Early Science radio, and DECam optical observations of a ~15 deg2 region around the nearby interacting galaxy cluster system A3391/95 to study the warm-hot gas in cluster outskirts and filaments, the surrounding large-scale structure and its formation process, the morphological complexity in the inner parts of the clusters, and the (re-)acceleration of plasma. We also used complementary Sunyaev-Zeldovich (SZ) effect data from thePlanck survey and custom-made Galactic total (neutral plus molecular) hydrogen column density maps based on the HI4PI and IRAS surveys. We relate the observations to expectations from cosmological hydrodynamic simulations from the Magneticum suite.Results. We trace the irregular morphology of warm and hot gas of the main clusters from their centers out to well beyond their characteristic radii,r 200. Between the two main cluster systems, we observe an emission bridge on large scale and with good spatial resolution. This bridge includes a known galaxy group but this can only partially explain the emission. Most gas in the bridge appears hot, but thanks to eROSITA’s unique soft response and large field of view, we discover some tantalizing hints for warm, truly primordial filamentary gas connecting the clusters. Several matter clumps physically surrounding the system are detected. For the “Northern Clump,” we provide evidence that it is falling towards A3391 from the X-ray hot gas morphology and radio lobe structure of its central AGN. Moreover, the shapes of these X-ray and radio structures appear to be formed by gas well beyond the virial radius,r 100, of A3391, thereby providing an indirect way of probing the gas in this elusive environment. Many of the extended sources in the field detected by eROSITA are also known clusters or new clusters in the background, including a known SZ cluster at redshiftz = 1. We find roughly an order of magnitude more cluster candidates than the SPT and ACT surveys together in the same area. We discover an emission filament north of the virial radius of A3391 connecting to the Northern Clump. Furthermore, the absorption-corrected eROSITA surface brightness map shows that this emission filament extends south of A3395 and beyond an extended X-ray-emitting object (the “Little Southern Clump”) towards another galaxy cluster, all at the same redshift. The total projected length of this continuous warm-hot emission filament is 15 Mpc, running almost 4 degrees across the entire eROSITA PV observation field. The Northern and Southern Filament are each detected at >4σ . ThePlanck SZ map additionally appears to support the presence of both new filaments. Furthermore, the DECam galaxy density map shows galaxy overdensities in the same regions. Overall, the new datasets provide impressive confirmation of the theoretically expected structure formation processes on the individual system level, including the surrounding warm-hot intergalactic medium distribution; the similarities of features found in a similar system in the Magneticum simulation are striking. Our spatially resolved findings show that baryons indeed reside in large-scale warm-hot gas filaments with a clumpy structure., Mar. 2021, 647, A2, A2, Scientific journal, 10.1051/0004-6361/202039590 - Refereed, Monthly Notices of the Royal Astronomical Society, Active gas features in three HSC-SSP CAMIRA clusters revealed by high angular resolution analysis of MUSTANG-2 SZE and XXL X-ray observations, Nobuhiro Okabe; Simon Dicker; Dominique Eckert; Tony Mroczkowski; Fabio Gastaldello; Yen-Ting Lin; Mark Devlin; Charles E Romero; Mark Birkinshaw; Craig Sarazin; Cathy Horellou; Tetsu Kitayama; Keiichi Umetsu; Mauro Sereno; Brian S Mason; John A ZuHone; Ayaka Honda; Hiroki Akamatsu; I-Non Chiu; Kotaro Kohno; Kai-Yang Lin; Elinor Medezinski; Satoshi Miyazaki; Ikuyuki Mitsuishi; Atsushi J Nishizawa; Masamune Oguri; Naomi Ota; Florian Pacaud; Marguerite Pierre; Jonathan Sievers; Vernesa Smolčić; Sara Stanchfield; Keigo Tanaka; Ryoichi Yamamoto; Chong Yang; Atsushi Yoshida, 31 Dec. 2020, 501, 2, 1701, 1732, Scientific journal, 10.1093/mnras/staa2330

- Refereed, MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, OXFORD UNIV PRESS, Central mass profiles of the nearby cool-core galaxy clusters Hydra A and A478, Okabe, N; Umetsu, K; Tamura, T; Fujita, Y; Takizawa, M; Matsushita, K; Fukazawa, Y; Futamase, T; Kawaharada, M; Miyazaki, S; Mochizuki, Y; Nakazawa, K; Ohashi, T; Ota, N; Sasaki, T; Sato, K; Tam, S. I, We perform aweak-lensing study of the nearby cool-core galaxy clusters, HydraA(z = 0.0538) and A478 (z = 0.0881), of which the brightest cluster galaxies (BCGs) host the powerful activities of active galactic nuclei (AGNs). For each cluster, the observed tangential shear profile is described well by either a single Navarro-Frenk-White model or a two-component model including the BCG as an unresolved point mass. For A478, we determine the BCG and its host-halo masses from a joint fit to weak-lensing and stellar photometry measurements. We find that the choice of initial mass functions (IMFs) can introduce a factor of 2 uncertainty in the BCG mass, whereas the BCG host-halo mass is constrained well by data. We perform a joint analysis of the weak-lensing and stellar kinematics data available for the Hydra A cluster, which allows us to constrain the central mass profile without assuming specific IMFs. We find that the central mass profile (r < 300 kpc) determined from the joint analysis is in excellent agreement with those from independent measurements, including dynamical masses estimated from the cold gas disc component, X-ray hydrostatic total mass estimates, and the central stella, 11 Mar. 2016, 456, 4, 4475, 4487, Scientific journal, 10.1093/mnras/stv2916

The X-ray temperatures of the three clusters are determined, respectively, at 7.2 (5.4-10.9), 6.5 (5.2-8.3), and 6.6 (5.7-7.7) keV (90% error), while the X-ray luminosities are determined to be 1.7, 1.3, and 8.3 x 10(44) ergs s(-1) in the 2-10 keV band. We also obtained significant constraints on the surface brightness profile assuming the beta-model and the King model (i.e., the beta-model with beta = 1) profiles. The mass of the cluster estimated from these X-ray data is smaller by a factor of 2-3 than the mass estimated from lens models for two of the clusters, CL 0500-24 and A370, while the two independent mass estimates are consistent with each other for CL 2244-02. We suspect that the major cause of mass discrepancy of CL 0500-24 and A370 is in the projection effect of substructures of these clusters.

We succeeded in measuring the turbulent motion at the center of the Perseus cluster and showed that the pressure due to the gas motion is small. In preparation for the future high-resolution spectroscopy, we performed simulations to examine the variety of gas motions and the accuracy of mass measurement in detail. Furthermore, we systematically studied X-ray properties of clusters that were newly discovered by the Subaru telescope to find that the simple theoretical model cannot explain the observed relationship between the gas temperature and luminosity and the evolution., url

Although the SXS observation was stopped in about a month by malfunction of the ASTRO-H spacecraft, the SXS instrument performed perfectly in orbit. We obtained a scientific result which suggests systematic errors introduced by the macroscopic motion of hot gas is not large in mass determination of cluster of galaxies, which is important for the study of dark energy using clusters We also performed X-ray searches of dark matter. We obtained most stringent constraint on the mixing angle of steel neutrinos in 1 to 20 keV mass range using the Galactic halo observations of Suzaku X-ray astronomy satellite., url

If clusters collide with each other, a huge amount of kinetic energy may be released and a certain fraction is expected to heat the gas and generate high-energy particles, and induce bulk and turbulent motions. To reveal the energy budget in the cluster evolution, we constrained the existence of very hot/non-thermal gas in clusters using the Suzaku satellite. From a systematic search for gas motions, we discovered the sign of large bulk motions in both regular and irregular clusters and a significant offset between the spatial distributions of gas and galaxies. Furthermore, we carried out simulations of spectral observations using high-resolution X-ray calorimeter onboard the ASTRO-H satellite and showed a possibility that we can measure the turbulent gas motion and the cluster mass with high accuracy., url

The existence of super-hot gas produced by cluster merging was confirmed, while hard X-ray emission from high-energy particles was not detected. In addition, density profiles of the cluster gas were calculated assuming that the gas is in a quasi-hydrostatic cooling state and compared with previous X-ray observations., url

Since the clusters of galaxies contain a large amount of hot gas, it is possible to measure the motion and temperature of the gas in detail. In particular, we have confirmed, for the first time, the presence of the hottest gas (with temperature of 0.3 billion degree) in the Universe inside the RXJ1347 cluster with the X-ray observations., url

また、野辺山45m電波望遠鏡を用いて銀河団RDCS0910のスニヤエフゼルドヴィッチ効果(SZ効果)の観測を行った。この天体は赤方偏移1.1に位置する超遠方銀河団であり、過去のX線観測から近傍銀河団と同程度の温度、質量をもつ高温ガスの存在が示唆されている。この天体からSZ効果の信号が検出されれば、電波で観測された最遠方の銀河団となるばかりか、銀河団ガスの進化を理解するうえで重要な手がかりが得られると期待される。今年度この天体の20時間の観測データを蓄横することができた。現在この天体からのSZ効果初検出を目指してデータ解析を進めている。, kaken - 特別研究員奨励費, 1998 - 2000, 98J05075, X線による遠方銀河団の観測的研究, 太田 直美, 日本学術振興会, 科学研究費助成事業 特別研究員奨励費, 東京大学, 2700000, 2700000, kaken
