cds-question@unistra.frradio-sourcesastronomical-object-identificationx-ray-sourcesWe report 20 and 6cm VLA deep observations of the CDF-S including the Extended CDF-S. We discuss the radio properties of 266 cataloged radio sources, of which 198 are above a 20cm completeness level reaching down to 43uJy at the center of the field. Survey observations made at 6cm over a more limited region cover the original CDF-S to a comparable level of sensitivity as the 20cm observations. Of 266 cataloged radio sources, 52 have X-ray counterparts in the CDF-S and a further 37 have counterparts in the E-CDF-S area not covered by the 1Ms exposure. Using a wide range of material, we have found optical or infrared counterparts for 254 radio sources, of which 186 have either spectroscopic or photometric redshifts. Three radio sources have no apparent counterpart at any other wavelength. Measurements of the 20cm radio flux density at the position of each CDF-S X-ray source detected a further 30 radio sources above a conservative 3{sigma} detection limit. X-ray and submillimeter observations have been traditionally used as a measure of AGN and star formation activity, respectively. These new observations probe the faint end of both the star formation and radio galaxy/AGN population, as well as the connection between the formation and evolution of stars and SMBHs.2008ApJS..179...71Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/179/71CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/139/369 : Chandra Deep Field South. 1 Ms catalog (Giacconi+, 2002)J/ApJS/161/21 : Extended Chandra Deep Field-South survey (Lehmer+, 2005)J/AJ/132/2409 : Deep ATLAS radio observations of CDFS (Norris+, 2006)J/AJ/131/1216 : Faint radio sources in the CDF-S ACS field (Afonso+, 2006)J/ApJ/179/114 : VLA 1.4GHz survey of E-CDF-S (Miller+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/179/71https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/179/71http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/179/71https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/179/71https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/179/71http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/179/71GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/179/71/table1 (CDF-S Radio Source Catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/179/71/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/179/71/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/179/71/table1?GETtext/xml+votable180.050000true52.79875-27.52897220.0055555555555555566/35934 35935 35957https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/179/71?format=asciiX-rayRadiodefaultJ/ApJS/179/71/table1CDF-S Radio Source CatalogrecnoRecord number assigned by the VizieR team.
