RX J2129.6+0005: Left: GMRT 610 MHz low resolution image in contours (white +ve and cyan −ve) is overlaid on the Chandra X-ray image (Obs ID 09370, 0.5−2 keV and resolution ~2′′) in colour. The contours are at −0.11,0.33,0.44,0.55,0.66,0.88 mJy beam^-1, and the beam is 11.6′′ × 10.6′′, p.a. 28°. The compact source at the centre marked by “×” has been subtracted. Right: the 610 MHz high resolution image in coutours (blue +ve and green −ve) is overlaid on the SDSS r-band image in colour. The contours are at −0.3,0.3,0.6,0.12,0.24,0.48 mJy beam^-1, and the beam is 9.3′′ × 6.5′′, p.a. 48°. The central compact source S1 is identified with the BCG. The contours from the left panel are also shown (black and cyan).
