Abell 1367: hierarchical growth through multiple mergers

Galaxy clusters grow hierarchically through the merger/accretion of smallersubstructures along filaments. The dynamically young cluster A1367 is one of thebest examples to study the cluster evolution because of its proximity and withabundant multiwavelength data. Additional to the main merger along the NWSEdirection and a merger shock/radio relic at the NW, we also find evidences ofanother countershock at the SE and the accretion of group/filament along theComaA1367 supercluster. We propose XMM observations to complete a coverage ofthe R500 radius of A1367 to 1) explore the unique case of an extended shockradio/tail interaction; 2) study the dynamics of the cluster/filament transitionregion; and 3) search for Xray tails/clumps associated with Halpha emission. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
