Left: False color RGB (R = g, G = r, B = z) Legacy survey image (Dey et al. 2019) centered on the galaxy cluster RMJ083056.4+322412.2 located at z_spec = 0.255. The image covers 600″ × 600″. The contours are [3, 5, 15, 20]×σ times the local noise level in the 400 MHz uGMRT map. The purple circle indicates the cluster center, and the red circles denote spectroscopically confirmed cluster members. Right: 400 MHz uGMRT image of two radio sources likely associated with RMJ083056.4+322412.2. The contour levels are the same as in the left panel. The beam size is shown in the white inset in the bottom left corner.
