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 (…
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…
Exploring chemical enrichment of the intracluster medium with the Line Emission Mapper
François Mernier, Yuanyuan Su, Maxim Markevitch +27
Synthesized in the cores of stars and supernovae, most metals disperse over cosmic scales and are ultimately deposited well outside the gravitational potential of their host galaxi…
Encounters of Merger and Accretion Shocks in Galaxy Clusters and their Effects on Intracluster Medium
Congyao Zhang, Eugene Churazov, Klaus Dolag +2
Several types/classes of shocks naturally arise during formation and evolution of galaxy clusters. One such class is represented by accretion shocks, associated with deceleration o…
Runaway Merger Shocks in Galaxy Cluster Outskirts and Radio Relics
Congyao Zhang, Eugene Churazov, William R. Forman +1
Moderately strong shocks arise naturally when two subclusters merge. For instance, when a smaller subcluster falls into the gravitational potential of a more massive cluster, a bow…
Standoff Distance of Bow Shocks in Galaxy Clusters as Proxy for Mach Number
Congyao Zhang, Eugene Churazov, William R. Forman +1
X-ray observations of merging clusters provide many examples of bow shocks leading merging subclusters. While the Mach number of a shock can be estimated from the observed density…
