In the upper and lower panels we present new radio maps of GRQ7 and GRG11, respectively. On the left-hand side is the NVSS 1.4 GHz colour map with 45″ resolution and rms of 0.45 mJy beam⁻¹. On the right-hand side, LoTSS 144 MHz 6″ colour map (rms ∼ 85 μJy beam⁻¹) is overlaid with LoTSS 20″ contours (rms ∼ 150 and 180 μJy beam⁻¹ for GRG11 and GRQ7 respectively). The contours are plotted at 3 rms × 2ⁿ (n = 0, 1, 2, 3...) for both maps. The blue ellipses in the bottom left corner of the respective images indicate the beam size. The angular length scale is given in the bottom right corner of the respective figures.
