I_R − I_X correlation of diffuse radio structures in A3016-3017. Left: Point-source subtracted Chandra image overlaid with radio contours from compact-source-subtracted high-resolution MeerKAT image after removing compact sources. The grid used to extract the surface brightness correlation is also presented. Right: I_R − I_X correlations for the A3017 mini-halo (in green), N-extension (in yellow), and bridge (in red). The values of X-ray surface brightness (I_X) are extracted from the point-sources-subtracted XMM-Newton image. The horizontal dashed line indicates the 3σ in the compact-source-subtracted high-resolution MeerKAT image.
