Fig. 1


Radio image of the radio relic found in Abell 3527-bis at 148, 323 and 608 MHz obtained with the GMRT. Contours are at (1,2,3,4,5,7,9,12,15,20,25) × 3σ with σ = 1400, 67 and 44 μJy beam-1, respectively. The resolutions of the three images are: 32′′×15′′ (148 MHz), 18″ × 8″ (323 MHz), and 9″ × 5″ (608 MHz). In the 608 MHz image the low-resolution (19″ × 15″) contours at 3σ (σ = 81μJy beam-1) are over-plotted in red. The last panel shows the spectral index map obtained as described in the text. Over-plotted in green are the regions used to calculate the spectral index in Fig. 6.

This figure is made of several images, please see below:
