Merger Shocks in Galaxy Clusters A665 and A2163 and Their Relation to Radio Halos

Abstract

We present Chandra gas temperature maps for two hot, intermediate-redshift clusters A665 and A2163. Both show strong temperature variations in their central r = 0.5h−1 Mpc regions, naturally interpreted as product of the subcluster mergers. The A665 map reveals a shock in front of the cool core, while the temperature structure of A2163 is more complicated… (More)
