Pairs of Giant Shock Waves (N-Waves) in Merging Galaxy Clusters
Congyao Zhang, Eugene Churazov, Irina Zhuravleva
When a subcluster merges with a larger galaxy cluster, a bow shock is driven ahead of the subcluster. At a later merger stage, this bow shock separates from the subcluster, becomin…
Collision of Merger and Accretion Shocks: Formation of Mpc-scale Contact Discontinuity in the Perseus Cluster
Congyao Zhang, Eugene Churazov, Klaus Dolag +2
Two Mpc-size contact discontinuities have recently been identified in the XMM-Newton and Suzaku X-ray observations of the outskirts of the Perseus cluster (Walker et al. 2020). The…
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…
