Notes. Columns are: (1) name of the giant radio galaxy from truncated sexagesimal RA,DEC (J2000) of the host galaxy; (2,3) right ascension and declination (J2000) of the host galaxy in degrees; (4) redshift of the host galaxy; (5) redshift type of the host galaxy: e for our own estimate, since no zphot is available in literature; p for photometric, being the average of values found in various references listed in Simonte et al. (2024), plus a few more recent ones (Beck et al. 2022; Wen & Han 2024; Zhou et al. 2025); s for spectroscopic, includung the recent DESI DR1 (DESI Collaboration 2025); for 4 objects marked as ’s*’ redshifts were obtained by us in 2015 and 2016 with the 10-m GranTeCan (GTC) on Canary Islands; (6) host type: G = galaxy, GP = galaxy pair, Q = quasar, QB = quasar with broad lines in SDSS spectrum, Qc = quasar candidate; (7) largest angular size in arcmin; (8) LLS in Mpc; (9) bending angle in degrees; (10) armlength ratio of brighter-to-fainter lobe; (11) survey used for flux integration: T = TGSS at 150 MHz, L = LOFAR at 145 MHz (Shimwell et al. 2022; Edler et al. 2023), MA = MeerKAT MALS DR2 at 1.27 MHz (Wagenveld et al. 2024), R = RACS at 888 and 1367 MHz (McConnell et al. 2020; Duchesne et al. 2023); A = ASKAP at 944 MHz (Norris et al. 2021) or SWAG-X (V. Moss, priv. comm) at 888 MHz; N = NVSS at 1.4 GHz (Condon et al. 1998); (12) total flux at the survey frequency; (13) decimal log of power at 145 MHz extrapolated from the survey frequency with α = −0.8; (14) code for provenance: P = from published literature (mainly Kuźmicz et al. 2018; Andernach et al. 2021; Oei et al. 2023a; Hardcastle et al. 2023; Simonte et al. 2024; Mostert et al. 2024; Koribalski 2025), N = new discovery by us, mostly from NVSS or LoTSS, or otherwise found by us in: MA = MeerKAT MALS DR2 at 1.27 MHz (Wagenveld et al. 2024), MW = MWA: EoR images (Offringa et al. 2016; Lynch et al. 2021), GLEAM (Hurley-Walker et al. 2017) or GLEAM-X DR1 (Hurley-Walker et al. 2022), A = ASKAP-EMU (Evolutionary Map of the Universe, Norris et al. (2021) or other ASKAP project, ED = LOFAR Euclid Deep Field North (Bondi et al. 2024), R = Radio Galaxy Zoo (Banfield et al. 2015; Wong et al. 2025), V = VICTORIA (Edler et al. 2023), n = mentioned in literature, but not as GRG. (15) environment flag: b = brightest cluster galaxy, m = cluster member galaxy, i = isolated galaxy (see sect. 3.4 for references). a GRGs J0101+5052 and J0843−0208 may have alternative hosts at lower redshift which would imply LLS values of 1.3 and 2.7 Mpc, respectively. However, we consider the hosts quoted here as the more likely ones.b The host of this GRG was wrongly identified by Oei et al. (2023a) as SDSS J013406.32+301537.2, but high-resolution images at 1.4 and 5 GHz by White et al. (2019) show it to be a restarted RG hosted by SDSS J013410.63+301537.7, also detected as X-ray source 4XMM J013410.7+301538.c These 7 sources are from Oei et al. (2023a) but are not in the public LoTSS DR2 footprint. For 3 of these we could not find suitable other radio surveys to determine ALR, BA and P145. Moreover, for J0722+4242 we adopt a host, SDSS J072238.26+424227.2, different from that in Oei et al. (2023a) since it coincides with a 0.7-mJy VLASS radio core.d Listed as J0905+5527 in Oei et al. (2023a) who propose SDSS J090528.26+552711.7 as the host, which is undetected in both LoTSS and VLASS. We propose the host DESI J136.4012+55.4346 as it has a radio core in both LoTSS and VLASS and is located closer to the GRG’s major axis. Its higher redshift implies a higher LLS.e Listed with zspec = 1.8857 in Debski et al. (2025) but the spectrum is very noisy and the redshift unreliable (M. Debski, priv.comm.)fOei et al. (2023a) propose SDSS J132002.53+602231.0 as the host which lies off due SW of the GRG’s major radio axis, is faint in LoTSS and undetected in VLASS. We propose SDSS J132024.00+602235.2 as the host, as it lies closer to the major source axis and has jet-like emission on both sides directed towards the outer lobes.g We agree with the host proposed by Hardcastle et al. (2023) but note that SDSS J160513.70+443347.8 may be another candidate. Its WISE color, redshift, and thus LLS, would be similar but its ALR∼1.05 would make it statistically less probable.hHardcastle et al. (2023) list a smaller LAS of 6.4′ and propose SDSS J163749.12+395038.3 with a strong compact radio source as the host. The DESI Legacy Survey DR10 resolves the SDSS object into a close pair of galaxies ∼1.5″ apart, and VLASS shows the fainter SW component to be the host of the radio source. Since this source is located off the GRG’s major radio axis we prefer SDSS J163753.66+394916.0 as the host which is closer to the symmetry centre of the GRG and has more AGN-like WISE colors. The redshift and LLS are similar for both hosts.
