JVLA image of the cluster Z2120. Left: JVLA D array image. The resolution is 33″ × 30″ and the rms noise is 0.06 mJy beam⁻¹. Labels mark the discrete sources in the cluster field. Right: low-resolution (55″ × 54″) JVLA contours after the compact sources subtraction overlaid over the X-ray Chandra image. Contours are drawn at (3,6...) × σ, with σ = 0.1 mJy beam⁻¹. The 2-σ negative contour is dashed. The green crosses mark the position of the three sources at the cluster centre, which have been subtracted.
