cds-question@unistra.frradio-galaxiesinfrared-photometryvisible-astronomybroad-band-photometryredshiftedWe describe a new estimate of the radio galaxy 1.4 GHz luminosity function and its evolution at intermediate redshifts (z~0.4). Photometric redshifts and color selection have been used to select B_J_<23.5 early-type galaxies from the Panoramic Deep Fields, a multicolor survey of two 25deg^2^ fields. Approximately 230 radio galaxies have then been selected by matching early-type galaxies with NVSS radio sources brighter than 5mJy. Estimates of the 1.4GHz luminosity function of radio galaxies measure significant evolution over the observed redshift range. For an {Omega}_M_=1 cosmology the evolution of the radio power is consistent with luminosity evolution where P(z)~P(0)(1+z)^K_L_^ and 3<K_L_<5. The observed evolution is similar to that observed for UVX and X-ray selected active galactic nuclei and is consistent with the same physical process being responsible for the optical and radio luminosity evolution of active galactic nuclei.2001AJ....121.2381Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/121/2381CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/65 : 1.4GHz NRAO VLA Sky Survey (NVSS) (Condon+ 1998)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/121/2381https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/121/2381http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/121/2381https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/121/2381https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/121/2381http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/121/2381GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/121/2381/table2 (Radio Galaxy Catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/121/2381/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/121/2381/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/121/2381/table2?GETtext/xml+votable180.050000true11.0325-29.7971390.0055555555555555564/1690 5/4161 4164 8939 6/16469 16640-16641 16660 16664 26847 26869-26871 27017-27020 27022-27023 27056 27058 27064 27066 27393 27396 27398 35583 35749-35754 35762-35763 35768 35770-35772 35774-35775https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/121/2381?format=asciiOpticalInfraredRadiodefaultJ/AJ/121/2381/table2Radio Galaxy CatalogNameNVSS source namemeta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
