Merger Activity and Radio Emission Within and Between Abell 2061 and 2067

We will observe the cluster pair A2061A2067, which show evidence for mergeractivity within and potentially between them. Our Chandra observation of thecenter of A2061 shows evidence for a merger with a subcluster just after firstcore passage. There is a shock, and a plume to the NE which is probably the coolcore gas from the merging subcluster. Our radio observations have detected abright radio relic to the SW of A2061, a central halo/relic, and a possiblerelic to the N of A2067. A pair of XMM observations will be used to determinethe properties of the shock in A2061, the dynamical state of this cluster, andthe merger history of A2067. We will search for Xrays near the position of theSW relic and for a filament of intercluster gas in the Cor.
