Left: SDSS i-band image of SDSSTG8102 shown in colour (grey). The overlaid magenta contours are from uGMRT 400 MHz, starting with 3σ_rms × [1, 2, 4,...], where σ_rms = 30.5 μJy beam⁻¹. The green contours are from the VLASS 3.0 GHz image at 2″ resolution, where the contour levels are 3σ_rms × [1, 2, 4], with σ_rms = 108 μJy beam⁻¹. The red circle indicates the BGG of the group. Middle: Same but for SDSSTG16393 with the same contour level from uGMRT and an rms of 32 μJy beam⁻¹. The green contours are from the VLASS 3.0 GHz map. Right: Same but for SDSSTG28674 with the same contour level as the upper panels and an rms of 28.7 μJy beam⁻¹. The green contours are from the VLASS map at a similar significance.
