Background SDSS image (composite from bands g, r and i) overlaid with white MSSS contours of the GRG at 2, 3, 4, 6 and 8 times the rms noise (34 mJy/beam). NVSS contours are overlaid in red at 3, 5, 10 and 20 times the rms noise (0.55 mJy/beam) revealing a bright part of the radio jet towards the north-east. The beam sizes are shown in the lower left. Galaxies with spectroscopic detections are marked with circles coloured by their corresponding redshift, where the AGN lies at a redshift of 0.05453 ± 1 × 10^-5. The dashed yellow box shows the area of Fig. 2.
