Constraining gas motion and non-thermal pressure beyond the core of the Abell 2029 galaxy cluster with XRISM
XRISM Collaboration, Marc Audard, Hisamitsu Awaki +137
We report a detailed spectroscopic study of the gas dynamics and hydrostatic mass bias of the galaxy cluster Abell 2029, utilizing high-resolution observations from XRISM Resolve.…
Do blue galaxy-clusters have hot intracluster gas?
Rana Misato, Yoshiki Toba, Naomi Ota +5
We present herein a systematic X-ray analysis of blue galaxy-clusters at discovered by the Subaru telescope. The sample consisted of 43 clusters identified by combining re…
Hundreds of weak lensing shear-selected clusters from the Hyper Suprime-Cam Subaru Strategic Program S19A data
Masamune Oguri, Satoshi Miyazaki, Xiangchong Li +9
We use the Hyper Suprime-Cam Subaru Strategic Program S19A shape catalog to construct weak lensing shear-selected cluster samples. From aperture mass maps covering ~deg$^…
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 +33
We present results from simultaneous modeling of high angular resolution GBT/MUSTANG-2 90 GHz Sunyaev-Zel'dovich effect (SZE) measurements and XMM-XXL X-ray images of three rich ga…
Halo Concentration, Galaxy Red Fraction, and Gas Properties of Optically-defined Merging Clusters
Nobuhiro Okabe, Masamune Oguri, Hiroki Akamatsu +9
We present multi-wavelength studies of optically-defined merging clusters, based on the Hyper Suprime-Cam Subaru Strategic Program. Luminous red galaxies, tracing cluster mass dist…
A large sample of shear selected clusters from the Hyper Suprime-Cam Subaru Strategic Program S16A wide field mass maps
Satoshi Miyazaki, Masamune Oguri, Takashi Hamana +13
We present the result of searching for clusters of galaxies based on weak gravitational lensing analysis of the ~deg area surveyed by Hyper Suprime-Cam (HSC) as a Sub…
X-ray properties of high-richness CAMIRA clusters in the Hyper Suprime-Cam Subaru Strategic Program field
Naomi Ota, Ikuyuki Mitsuishi, Yasunori Babazaki +13
We present the first results of a pilot X-ray study of 37 rich galaxy clusters at in the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP) field. Diffuse X-ray emiss…
Multiwavelength study of X-ray Luminous Clusters in the Hyper Suprime-Cam Subaru Strategic Program S16A field
Keita Miyaoka, Nobuhiro Okabe, Takao Kitaguchi +34
We present a joint X-ray, optical and weak-lensing analysis for X-ray luminous galaxy clusters selected from the MCXC (Meta-Catalog of X-Ray Detected Clusters of Galaxies) cluster…
Exploring the bridge between A3556 and A3558 in the Shapley Supercluster
E. Ursino, M. Galeazzi, A. Gupta +4
Looking at the region connecting two clusters is a promising way to identify and study the Warm-Hot Intergalactic Medium. Observations show that the spectrum of the bridge between…
Exploring Hot Gas at Junctions of Galaxy Filaments with Suzaku
Ikuyuki Mitsuishi, Hajime Kawahara, Norio Sekiya +3
We performed five pointing observations with Suzaku to search for hot gases associated with the junctions of galaxy filaments where no significant diffuse X-ray sources were detect…
Metals in the Intracluster Medium of MS 1512.4+3647 Observed with Suzaku: Implications for the Metal Enrichment History
Yuya Shimoda, Madoka Kawaharada, Kosuke Sato +5
The cluster of galaxies MS 1512.4+3647 (z=0.372) was observed with Suzaku for 270 ks. Besides the Fe abundance, the abundances of Mg, Si, S, and Ni are separately determined for th…
An X-ray study of the galactic-scale starburst-driven outflow in NGC 253
Ikuyuki Mitsuishi, Noriko Y. Yamasaki, Yoh Takei
X-ray properties of hot interstellar gas in a starburst galaxy NGC 253 were investigated to gain a further understanding of starburst-driven outflow activity by XMM-Newton and Suza…
Fe K line complex in the nuclear region of NGC 253
Ikuyuki Mitsuishi, Noriko Y. Yamasaki, Yoh Takei
A bright, nearby edge-on starburst galaxy NGC 253 was studied using the Suzaku, XMM and Chandra X-ray observatories. We detected with Suzaku and XMM complex line structure of Fe K,…
