We present results from an X-ray and radio study of the merging galaxycluster Abell 115. We use the full set of 5 Chandra observations taken of A115to date (360 ks total integration) to construct high-fidelity temperature andsurface brightness maps. We also examine radio data from the Very Large Arrayat 1.5 GHz and the Giant Metrewave Radio Telescope at 0.6 GHz. We propose thatthe high X-ray spectral temperature between the subclusters results from theinteraction of the bow shocks driven into the intracluster medium by the motionof the subclusters relative to one another. We have identified morphologicallysimilar scenarios in Enzo numerical N-body/hydrodynamic simulations of galaxyclusters in a cosmological context. In addition, the giant radio relic featurein A115, with an arc-like structure and a relatively flat spectral index, islikely consistent with other shock-associated giant radio relics seen in othermassive galaxy clusters. We suggest a dynamical scenario that is consistentwith the structure of the X-ray gas, the hot region between the clusters, andthe radio relic feature.
