Abell 2142. Radio contours at 1283 MHz, starting from 3σ_I and scaling by a factor of 2, are overlaid in both maps. The known radio galaxies and two out of three halo components are labeled with their names. Only BCG1 is pointed in red in panel (a), as BCG2 does not show evidence of any radio emission. Panel (a): XMM Cluster Outskirts Project (X-COP) adaptively smoothed, vignetting-corrected and background-subtracted X-ray surface brightness in the range [0.7 − 1.2] keV. Panel (b): Total intensity (Stokes I) map of A2142 at 1283 MHz. It is appreciable the emission from both radio galaxies and the two radio halos, H1 and H2. Dashed circle corresponds to the reference distance of 1 Mpc from the cluster centre. The spatial scales and resolution beam of 20″ × 20″ (33.4 kpc) are reported on the edges of the image.
