Sloshing Motions in Abell 3571 Revealed by XRISM/Resolve Velocity Mapping
Itsuki Aihara, Congyao Zhang, Sora Nakajima +12
Minor mergers can induce sloshing motions in the intracluster medium, leaving characteristic signatures in the thermodynamic structure and gas kinematics of cluster cores. Abell 35…
Kinematics of Weak Cool-Core Cluster A3571 Observed with XRISM: Low Cooling Rate Balanced by Low Heating Rate
Hannah McCall, Irina Zhuravleva, Kyoko Matsushita +10
Most XRISM galaxy cluster observations to date have focused on AGN feedback or actively merging systems. The weak cool-core cluster A3571 was observed in four XRISM Cycle 1 pointin…
Decoding AGN Feedback with X-arithmetic: From Morphology to Physical Mechanisms
Hannah McCall, Irina Zhuravleva, Eugene Churazov +4
Feedback from Active Galactic Nuclei (AGN) is a key process in the evolution of massive halos in the Universe. New observational information on feedback is crucial for improving th…
Mapping the Intracluster Medium in the Era of High-resolution X-ray Spectroscopy
Congyao Zhang, Irina Zhuravleva, Maxim Markevitch +24
High-resolution spectroscopy in soft X-rays will open a new window to map multiphase gas in galaxy clusters and probe physics of the intracluster medium (ICM), including chemical e…
