cds-question@unistra.frsurveysgalaxiescatalogsradio-sourcesvisible-astronomysloan-photometryredshiftedWe present the Large Area Radio Galaxy Evolution Spectroscopic Survey (LARGESS), a spectroscopic catalogue of radio sources designed to include the full range of radio AGN populations out to redshift z~0.8. The catalogue covers ~800deg^2^ of sky, and provides optical identifications for 19179 radio sources from the 1.4GHz Faint Images of the Radio Sky at Twenty-cm (FIRST) survey down to an optical magnitude limit of i_mod_<20.5 in Sloan Digital Sky Survey (SDSS) images. Both galaxies and point-like objects are included, and no colour cuts are applied. In collaboration with the WiggleZ and Galaxy And Mass Assembly (GAMA) spectroscopic survey teams, we have obtained new spectra for over 5000 objects in the LARGESS sample. Combining these new spectra with data from earlier surveys provides spectroscopic data for 12329 radio sources in the survey area, of which 10 856 have reliable redshifts. 85 per cent of the LARGESS spectroscopic sample are radio AGN (median redshift z=0.44), and 15 per cent are nearby star-forming galaxies (median z=0.08). Low-excitation radio galaxies (LERGs) comprise the majority (83 per cent) of LARGESS radio AGN at z<0.8, with 12 per cent being high-excitation radio galaxies (HERGs) and 5 per cent radio-loud QSOs. Unlike the more homogeneous LERG and QSO sub-populations, HERGs are a heterogeneous class of objects with relatively blue optical colours and a wide dispersion in mid-infrared colours. This is consistent with a picture in which most HERGs are hosted by galaxies with recent or ongoing star formation as well as a classical accretion disc.2017MNRAS.464.1306Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/464/1306CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/147 : The SDSS Photometric Catalogue, Release 12 (Alam+, 2015)VII/241 : The 2dF QSO Redshift Survey (Croom+ 2004)VIII/65 : 1.4GHz NRAO VLA Sky Survey (NVSS) (Condon+ 1998)VIII/92 : The FIRST Survey Catalog, Version 2014Dec17 (Helfand+ 2015)J/MNRAS/372/425 : 2dF-SDSS Luminous Red Galaxy Survey, 2SLAQ (Cannon+, 2006)J/MNRAS/401/1429 : WiggleZ dark energy survey (DR1) (Drinkwater+, 2010)J/MNRAS/452/2087 : Galaxy And Mass Assembly (GAMA): DR2 (Liske+, 2015)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/464/1306https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/464/1306http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/464/1306https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/464/1306https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/464/1306http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/464/1306GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/464/1306/table10 (Main LARGESS data table)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/464/1306/table10?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/464/1306/table10?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/464/1306/table10?GETtext/xml+votable180.050000true0.01630.281560.0055555555555555564/256-257 512-514 1621-1623 1625 1628-1629 1642 1685 1691-1692 1694 1707-1708 1710 1712-1714 1962 5/1036-1037 1040-1042 2060 2080 4324-4326 4329 4437-4438 4441-4442 4453-4454 4457-4458 4501-4503 4505-4506 4517-4518 4520-4522 4693-4694 4697-4698 4709-4710 4713-4714 4757-4758 4760-4762 4773-4774 5461-5463 5465 5468-5469 5801-5802 6399 6477-6479 6481-6483 6505-6506 6520-6521 6523-6524 6549-6550 6553-6554 6563 6565-6566 6572 6739 6745-6748 6757-6759 6761-6763 6772 6774-6775 6780-6782 6805-6807 6809-6810 6813 6821-6823 6825-6827 6838 6844-6846 6860-6862 6864-6866 6881 6912 7842 7854 9200 9202 11261-11263 6/0-2 4128 4132-4133 4135 4152-4153 4155-4158 4172-4174 4176-4178 4192-4194 8244-8246 8248-8250 8258 8264-8266 8324-8326 8328-8330 17211 17214 17287 17291 17293-17295 17308-17310 17313-17315 17320-17321 17323-17326 17328-17330 17405-17407 17661-17663 17723 17725-17727 17741-17743 17745-17747 17756-17758 17761-17763 17772-17774 17776-17777 17805-17807 17809-17811 17820-17822 17825-17827 17836-17838 17840-17841 17856-17858 17981-17983 17997-17999 18001-18003 18017-18019 18028-18030 18032-18034 18040 18061-18063 18065-18067 18076-18078 18092 18094 18096-18098 18112-18114 18176-18178 18685-18687 18749-18751 18765-18767 18769-18771 18780-18782 18785-18787 18796-18798 18800-18802 18804 18808 18823 18829-18831 18833-18835 18844-18846 18849-18851 18860-18862 18864-18866 18880-18882 19005-19007 19021-19023 19025-19027 19036-19038 19052-19054 19056-19058 19085-19087 19089-19091 19100-19102 19109 19111 19120-19122 19136-19138 19200-19202 19456-19458 21837-21839 21841-21843 21868-21869 21881 21884 23182-23183 23201-23203 23212 23214 23216 23218 25589-25591 25595 25853-25855 25887 25903 25907 25923 25989 25997-25999 26017-26019 26028-26030 26032-26033 26036-26037 26088-26089 26100-26102 26104-26106 26173-26175 26189-26191 26193-26195 26204 26209-26211 26220-26222 26224-26226 26249-26251 26257-26259 26268-26270 26296 26298 26304-26306 26368-26370 26436-26437 26877-26879 26941-26943 26949-26951 26977-26979 26996-26998 27002 27019 27021-27023 27025-27027 27041-27043 27094 27132-27134 27197-27199 27213-27215 27217-27219 27233-27235 27244-27246 27248-27249 27261 27275 27277-27279 27281-27283 27297-27299 27344 27346-27347 27356 27358-27359 27388-27390 27452-27453 27468 27472-27474 27488-27490 27521 27536-27538 27552 27554 27652-27654 27656-27658 27786 27808 27810 31374 31410 31422 36759 36765 36806 36812 36861-36863 40957-40959 45039 45043https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/464/1306?format=asciiOpticalRadiodefaultJ/MNRAS/464/1306/table10Main LARGESS data tablerecnoRecord number assigned by the VizieR team.
