BeppoSAXtemperature maps of galaxy clusters in the Corona Borealis supercluster: A2061, A2067 and A2124

Abstract

In this paper we present the analysis of BeppoSAX observations of the cluster pairs A2061–A2067 and A2122–A2124, located in the Corona Borealis supercluster, which have been selected as candidate merging clusters. The aim of this work is to study the physics of the intracluster medium and to look for the possible presence of merging signatures. We derived the global temperatures and abundances and the temperature profiles and maps for these clusters. We do not find any significant evidence of interaction between the clusters forming the pairs, but we detect a candidate shock inside A2061. On the basis of the X‐ray and optical properties of this cluster we propose a scenario in which a group is falling inside A2061. This interaction is in the phase in which the cores have not yet met and in which the formation of a shock is expected.
