Multiple shock fronts in RBS 797: the Chandra window on shock heating in galaxy clusters
F. Ubertosi, M. Gitti, F. Brighenti +11
Using 427 ks of Chandra observations, we present a study of shock heating and ICM cooling in the galaxy cluster RBS 797. We discover three nested pairs of weak shocks at roug…
HST and HSC Weak-lensing Study of the Equal-mass Dissociative Merger CIZA J0107.7+5408
Kyle Finner, Scott W. Randall, M. James Jee +6
A dissociative merger is formed by the interplay of ram pressure and gravitational forces, which can lead to a spatial displacement of the dark matter and baryonic components of th…
Gas sloshing and cold fronts in pre-merging galaxy cluster Abell 98
Arnab Sarkar, Scott Randall, Yuanyuan Su +10
We present deep Chandra observations of the pre-merger galaxy cluster Abell 98. Abell 98 is a complex merging system. While the northern (A98N) and central subclusters (A98S) are m…
Discovery of a pre-merger shock in an intercluster filament in Abell 98
Arnab Sarkar, Scott Randall, Yuanyuan Su +11
We report the first unambiguous detection of an axial merger shock in the early-stage merging cluster Abell 98 using deep (227 ks) Chandra observations. The shock is about 420 kpc…
