cds-question@unistra.frradio-sourcesastronomical-object-identificationsurveysredshiftedinfrared-photometryWe present the optical and infrared identifications of the 266 radio sources detected at 20cm with the Very Large Array in the Chandra Deep Field-South. Using deep i-band Advanced Camera for Surveys, R-band Wide Field Imager, K-band SOFI NTT, K-band ISAAC VLT and Spitzer imaging data, we are able to find reliable counterparts for 254 (~95%) VLA sources. Twelve radio sources remain unidentified, and three of them are "empty fields". Using literature and our own data we are able to assign redshifts to 186 (~70%) radio sources: 108 are spectroscopic redshifts and 78 are reliable photometric redshifts. Based on the rest-frame colors and morphological distributions of the host galaxies, we find evidences for a change in the submillijansky radio source population: (1) above ~0.08mJy early-type galaxies are dominating and (2) at flux densities below ~0.08mJy, starburst galaxies become dominant.2008ApJS..179...95Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/179/95CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/65 : 1.4GHz NRAO VLA Sky Survey (NVSS) (Condon+ 1998)II/253 : Chandra Deep Field South: multi-colour data (Wolf+, 2008)J/A+A/377/442 : Chandra Deep Field South: R-band photometry (Wolf+, 2001)J/A+A/428/1043 : Redshifts from VIMOS VLT Deep Survey (Le Fevre+, 2004)J/ApJS/155/271 : Chandra Deep Field-South: Optical spectroscopy (Szokoly+,J/ApJS/161/21 : Extended Chandra Deep Field-South survey (Lehmer+, 2005)J/A+A/434/53 : GOODS-South Field redshifts (Vanzella+, 2005)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)J/ApJS/179/71 : VLA survey of the CDF-S I.
