cds-question@unistra.fractive-galactic-nucleiquasarsradio-sourcesradio-galaxiesFrom visual inspection of the three LOw-Frequency ARray (LOFAR) deep fields, namely the Bootes, ELAIS-N1, Lockman Hole, covering a total area of 95 deg^2^, we compile a list of 1609 radio galaxies (RGs) with a projected angular size larger than about 30 arcsec. We present their host galaxies with either spectroscopic (when available) or else photometric redshift estimates culled from various different references, and use these to estimate their projected linear sizes. We compare the radio, optical properties of GRGs with those of a control sample of smaller RGs, and explored their environment in terms of the surface number density of neighbouring galaxies within these surveys. Integrated flux densities and radio luminosities were determined for a subset of RGs through available survey images at 50, 150, 610, and 1400 MHz to compute integrated spectral indices. We find that GRGs preferentially reside in sparser environments compared to their smaller counterparts. Only 3.6% of the GRGs reside within a 3D comoving distance of 5 Mpc from a previously reported galaxy cluster, and that larger sources exhibit steeper integrated spectral indices, suggesting that GRGs are late-stage versions of RGs.2024A&A...686A..21Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/686/A21CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/328 : AllWISE Data Release (Cutri+ 2013)II/365 : CatWISE2020 catalog (updated version 28-Jan-2021) (Marocco+, 2021)II/357 : The Dark Energy Survey (DES): Data Release 1 (Abbott+, 2018)VII/292 : DESI Legacy Imaging Surveys DR8 (Duncan, 2022)J/MNRAS/515/2032 : LoTSS Bootes Deep Field Giant Radio GalaxiesJ/A+A/672/A178 : Radio galaxy alignment in ELAIS-N1 (Simonte+, 2023)J/A+A/648/A2 : LoTSS Deep Fields DR1 ELAIS-N1 deep field (Sabater+, 2021)J/A+A/648/A3 : LoTSS Deep Fields DR1 ELAIS-N1 & Lockman HoleJ/A+A/648/A4 : LoTSS Deep Fields DR1 photometric redshifts (Duncan+, 2021)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/686/A21https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/686/A21http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/686/A21https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/686/A21https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/686/A21http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/686/A21GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/686/A21/tablea1 (Radio and optical data for 1609 Extended Radio Galaxies (ERG))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/686/A21/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/686/A21/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/686/A21/tablea1?GETtext/xml+votable180.050000true154.203458.05440.0055555555555555564/379 634 5/1511 1520 1522-1523 1528-1529 1860-1861 2286-2287 2298 2628-2630 2880-2881 6/5951 5993-5996 5998 6036-6037 6039 6041-6043 6053 6061 6063 6084 6086 6120-6122 6124 7429 7431 7448-7449 7451-7454 7488-7490 9133 9135 9138-9139 9142-9143 9186 9981 9983 10123 10126-10127 10160 10162 10168 10501 10503 10509 10524-10525 10560 10562 11348-11349 11351 11357 11528-115299.54153977050123e-26 9.54153977050123e-26https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/686/A21?format=asciiRadiodefaultJ/A+A/686/A21/tablea1Radio and optical data for 1609 Extended Radio Galaxies (ERG)recnoRecord number assigned by the VizieR team.
