cds-question@unistra.frradio-sourcesredshiftedWe have used the Australia Telescope Compact Array (ATCA) to search for faint radio sources in a ~3deg^2^ region of sky covered by the 2dF Galaxy Redshift Survey (2dFGRS, Cat. <VII/226>). Over the region surveyed, the 1{sigma} noise level at 1.4GHz ranges from 20Jy to 1mJy. The survey region includes 365 2dFGRS galaxies, of which 316 have good-quality spectra (176 early-type galaxies or active galactic nuclei, and 140 star-forming galaxies). The fraction of 2dFGRS galaxies detected as radio sources in our survey rises from ~4% at a 3{sigma} detection limit of 0.3mJy to 12% at 75{mu}Jy, with roughly equal numbers of star-forming galaxies and active galactic nuclei (AGNs) being detected.2004MNRAS.352.1245Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/352/1245CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/226 : The 2dF Galaxy Redshift Survey 100k Data Release (2dFGRS Team, 2001)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/352/1245https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/352/1245http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/352/1245https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/352/1245https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/352/1245http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/352/1245GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/352/1245/table3 (2dFGRS radio identifications)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/352/1245/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/352/1245/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/352/1245/table3?GETtext/xml+votable180.050000true353.7117083-28.64233330.005555555555555556Cone search capability for table J/MNRAS/352/1245/table4 (2dFGRS radio upper limits)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/352/1245/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/352/1245/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/352/1245/table4?GETtext/xml+votable180.050000true353.3919583-27.744750.0055555555555555565/4140 6/16564 16566 16568-16569 16572https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/352/1245?format=asciiOpticalRadiodefaultJ/MNRAS/352/1245/table32dFGRS radio identifications2dFGRS2dFGRS (<VII/226>) namemeta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
