Non-Thermal Pressure due to Gas Motions in the Intracluster Medium: Confronting XRISM/Resolve with TNG-Cluster Simulations
Erwin T. Lau, Naomi Ota, Daisuke Nagai
Intracluster medium (ICM) gas motions probe cluster assembly, feedback, and non-thermal pressure support, but recent XRISM observations reveal velocity dispersions and non-thermal…
Kinetic structure of the intracluster medium across nearby clusters observed with XRISM
Naomi Ota, Erwin T. Lau, Satoshi Yamada +2
XRISM/Resolve is building a sample of galaxy clusters with directly measured ICM gas motions, revealing diverse projected dynamical states. We compile 45 XRISM/Resolve measurements…
XRISM Observations of Abell 1795: Evidence for Low Turbulence and Resonant Scattering
Arnab Sarkar, Eric D. Miller, Brian McNamara +10
We present high-resolution X-ray spectroscopic observations of the cool-core galaxy cluster Abell~1795 obtained with XRISM/Resolve. The cluster was observed with two deep pointings…
XRISM-Subaru views of Abell 754: an off-axis, near-line-of-sight merging cluster
Nobuhiro Okabe, Yuki Omiya, Kazuhiro Nakazawa +4
We report a weak-lensing (WL) mass measurement for the merging cluster Abell 754 and impose constraints on the merger trajectory. The trajectory analysis adopts a two-body model wi…
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.…
Unveiling the Galaxy Cluster - Cosmic Web Connection with X-ray observations in the Next Decade
Stephen A. Walker, Daisuke Nagai, A. Simionescu +35
In recent years, the outskirts of galaxy clusters have emerged as one of the new frontiers and unique laboratories for studying the growth of large scale structure in the universe.…
