Z5247: Top: GMRT 610 MHz high resolution image in contours (red +ve and cyan −ve) overlaid on SDSS r-band image in grey-scale. The contours are at −0.09,0.09,0.18,0.36,0.72,1.44,2.88,5.76 mJy beam^-1. The beam at 610 MHz is 6.2′′ × 5.2′′, p.a. 56°. The discrete radio sources in the cluster region (A to I), the relic and the two BCGs (1 and 2) are labelled. The extent of the X-ray emission from the cluster ICM is shown by the black contour. Bottom left: the Chandra X-ray image (Obs ID 11727, 0.5−2 keV and resolution ~4′′) of Z5247 is shown in colour overlaid with the contours of the 60′′×60′′ resolution 610 MHz image (black +ve and cyan −ve) made after the subtraction of the discrete sources. The contours are at −0.9,0.9,1,1.2,1.8,2.4,3,4 mJy beam^-1. The features in the X-rays are labelled in green (P1, P2 and NW Extension) and the positions of the BCGs (“×”) and of the discrete radio sources (“+”) are marked. Bottom right: the 60′′ × 60′′ resolution 610 MHz image is shown in grey-scale with the same contours as in the left panel.
