cds-question@unistra.frsurveysradio-sourcesactive-galactic-nucleiredshiftedWe describe deep radio imaging at 1.4GHz of the 1.3-deg^2^ Subaru/XMM-Newton Deep Field (SXDF), made with the Very Large Array in B and C configurations. We present a radio map of the entire field, and a catalogue of 505 sources covering 0.8deg^2^ to a peak flux density limit of 100uJy. Robust optical identifications are provided for 90 per cent of the sources, and suggested identifications are presented for all but 14 (of which seven are optically blank, and seven are close to bright contaminating objects). We show that the optical properties of the radio sources do not change with flux density, suggesting that active galactic nuclei (AGN) continue to contribute significantly at faint flux densities. We test this assertion by cross-correlating our radio catalogue with the X-ray source catalogue and conclude that radio-quiet AGN become a significant population at flux densities below 300uJy, and may dominate the population responsible for the flattening of the radio source counts if a significant fraction of them are Compton-thick.2006MNRAS.372..741Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/372/741CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/634/861 : Old passively evolving galaxies at z=1 in SXDF (Yamada+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/372/741https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/372/741http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/372/741https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/372/741https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/372/741http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/372/741GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/372/741/table3 (The full 100 microJy catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/372/741/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/372/741/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/372/741/table3?GETtext/xml+votable180.050000true34.6138333-4.91035830.0055555555555555566/17677 17679 17688 17690https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/372/741?format=asciiOpticalRadiodefaultJ/MNRAS/372/741/table3The full 100 microJy cataloguerecnoRecord number assigned by the VizieR team.
