The six known GRGs larger than 5 Mpc. Images from LoTSS DR2 are arranged in increasing order of linear size from left to right, with their host galaxy marked by a magenta cross. To save space, all radio galaxies have been rotated so that their major radio axis is vertical. The GRGs are (with their LAS in arcmin, LLS in Mpc, and real PA on the sky, from N through E, listed in parentheses): J1108+2916 (11.6′, > 5.2, 31°), J0901+4420 (11.7′, > 5.4, 170°), J1753−0332 (13.6′, 5.46, 152°), J0103+2305 (24.1′, > 5.9, 101°), J1529+6015 (13.2′, 6.16, 26°), and J0838+5327 (17.2′, 6.6, 22°). The lower limits for the LLS values are due to assuming the lowest reasonable host redshift.
