XRISM reveals sloshing-driven gas motions in the core of Abell 2029
Yuusuke Uchida, Yuna Saito, Naomi Ota +13
We investigate the velocity structure of the intracluster medium (ICM) in the core of the relaxed cool-core cluster Abell 2029 using XRISM Resolve spectroscopy. We analyze combined…
XRISM Reveals a Kinematically Coherent Core System of the Nearby Cool-Core Cluster Abell 2199
Kazunori Suda, Kyoko Matsushita, Kosuke Sato +14
We present the results of a deep 251 ks XRISM/Resolve observation of the cool core of the galaxy cluster Abell 2199. From the integrated spectrum of the central Reso…
X-ray line diagnostics of the multi-phase gas in the Centaurus cluster core with XRISM/Resolve
Marie Kondo, Kotaro Fukushima, Kazunori Suda +18
We report the multi-temperature structure of the intracluster medium (ICM) in the Centaurus cluster core observed with XRISM/Resolve. Thanks to its high energy resolution, Resolve…
Unveiling Chemical Enrichment in the Abell 2029 Core with XRISM, XMM-Newton, and Chandra
Arnab Sarkar, Eric D. Miller, Brian McNamara +6
We present new measurements of the chemical abundance pattern in the core of the nearby galaxy cluster Abell~2029, based on XRISM observations with Resolve (37 ks) and Xtend (500 k…
Solving the cooling flow problem with combined jet-wind AGN feedback
Aoyun He, Feng Yuan, Suoqing Ji +6
Active galactic nucleus (AGN) feedback is widely viewed as the most promising solution to the long-standing cooling flow problem in galaxy clusters, yet previous models prescribe j…
Comparing XRISM cluster velocity dispersions with predictions from cosmological simulations: are feedback models too ejective?
XRISM Collaboration, Marc Audard, Hisamitsu Awaki +147
The dynamics of the intra-cluster medium (ICM), the hot plasma that fills galaxy clusters, are shaped by gravity-driven cluster mergers and feedback from supermassive black holes (…
XRISM Reveals Complex Multi-Temperature Structures in the Abell 2029 Galaxy Cluster
Arnab Sarkar, Eric Miller, Naomi Ota +9
We present 500 ks XRISM observations covering the central and two northern regions of the Abell 2029 galaxy cluster. Resolve enables us to distinguish multiple emission lines…
Electron-Ion Equilibration in the Merging Galaxy Cluster A665
Christian Norseth, Daniel R. Wik, Craig L. Sarazin +2
Galaxy cluster mergers drive powerful shock fronts that heat the intracluster medium (ICM) and accelerate particles, redistributing the energy in a merger. A665 is one of only a fe…
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.…
