Close-up view of an ongoing merger between the NGC 4839 group and the Coma cluster - a post-merger scenario
N. Lyskova, E. Churazov, C. Zhang +5
We study a merger of the NGC 4839 group with the Coma cluster using X-ray observations from the XMM-Newton and Chandra telescopes. X-ray data show two prominent features: (i) a lon…
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…
Generation of Internal Waves by Buoyant Bubbles in Galaxy Clusters and Heating of Intracluster Medium
Congyao Zhang, Eugene Churazov, Alexander A. Schekochihin
Buoyant bubbles of relativistic plasma in cluster cores plausibly play a key role in conveying the energy from a supermassive black hole to the intracluster medium (ICM) - the proc…
