Cutouts of the LOFAR deep fields image around our GRGs at 150 MHz with 3 and 24-σ_rms red contours superimposed. The resolution of the images is 6″. The cyan circle identifies the position of the host galaxy. The bar in the bottom-right corner represents an angular size of 1′, while the name and the largest linear size (in Mpc) of the GRGs are reported in the top-left and top-right corners, respectively.
