Beppo-SAX temperature maps of galaxy clusters in the Corona Borealis supercluster: A2061, A2067 and A2124

摘要

In this paper we present the analysis of Beppo-SAX observations of thecluster pairs A2061-A2067 and A2122-A2124, located in the Corona Borealissupercluster, which have been selected as candidate merging clusters. The aimof this work is to study the physics of the intracluster medium and to look forthe possible presence of merging signatures. We derived the global temperatures and abundances and the temperatureprofiles and maps for these clusters. We do not find any significant evidenceof interaction between the clusters forming the pairs, but we detect acandidate shock inside A2061. On the basis of the X-ray and optical propertiesof 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 encountered yetand in which the formation of a shock is expected.
