Fig. 2.
SDSS i, r, g image of Abell 1319 with LOFAR radio emission overlaid as contours. LOFAR high-resolution emission (11 arcsec × 6 arcsec) is shown by red contours [3, 5, 16, 64, 128, 256, 512] × σ where σ = 170 μJy beam−1. The smoothed Chandra X-ray image is shown in blue-magenta and as blue contours. Cluster galaxies with known spectroscopic redshifts are indicated by coloured rings, where the colour represents redshift.
