Caption: Figure 8.

Left: color-composite Subaru image with enhanced radio (green) and X-ray (red) emissions. Radio emissions are from GRMT observations (Bonafede et al. 2014), and X-ray emissions are from XMM-Newton. The overlaid convergence contours (white) peak in the X-ray-emitting ICM, with the highest contour enveloping the BCG. The mass is distributed along a direction similar to the axis connecting the radio relics. The HST F814W pointing is outlined in light blue. Right: mass distribution overlaid on the Subaru cluster member catalog luminosity density. The luminosity density has a bimodal distribution in the cluster center, with the NWc luminosity peak consistent with the mass peak. The SEc luminosity peak has no clear mass counterpart in the Subaru mass reconstruction.
