Spectral index profiles, calculated in the two frequency ranges, at high-resolution. Left: Profiles for the NE relic. The low-frequency profile shows two peak in spectral index, one at the position of the merger shock and one at the position of the substructure. The high-frequency profile differs, showing a flat behavior along the regions overlaid on the bright bar substructure. Both profiles show a sharp drop of spectral index into downstream regions. Right: Profiles for the SW relic. Both profile show a similar trend, decreasing toward the cluster center.
