cds-question@unistra.frsurveysradio-galaxiesx-ray-sourcesIn order to determine the relationship between the faint X-ray and faint radio source populations, and hence to help understand the X-ray and radio emission mechanisms in those faint source populations, we have made a deep 1.4-GHz Very Large Array radio survey of the 13h+38{deg} XMMNewton/ROSAT X-ray Survey Area. From a combined data set of 10-h, B-configuration data and 14-h, A-configuration data, maps with 3.35-arcsec resolution and a noise limit of 7.5Jy were constructed. A complete sample of 449 sources was detected within a 30-arcmin diameter region above a 4 detection limit of 30Jy, at the map centre, making this one of the deepest radio surveys at this frequency. The differential source count shows a significant upturn at submilliJansky flux densities, similar to that seen in other deep surveys at 1.4GHz (e.g. the Phoenix survey, Cat. <J/MNRAS/296/839>), but larger than that seen in the Hubble Deep Field (HDF) which may have been selected to be underdense. This upturn is well modelled by the emergence of a population of medium-redshift star-forming galaxies which dominate at faint flux densities. The brighter source counts are well modelled by active galactic nuclei.2004MNRAS.352..131Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/352/131CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/xmm : XMM-Newton Observation Log (XMM-Newton SOC, 2002)VIII/65 : 1.4GHz NRAO VLA Sky Survey (NVSS) (Condon+ 1998)J/A+A/424/371 : 1.4GHz First Look Survey (FLS) (Morganti+, 2004)J/MNRAS/342/802 : Chandra survey of 13-h XMM/ROSAT survey (McHardy+, 2003)J/MNRAS/296/839 : Phoenix Deep Survey: 1.4-GHz source counts (Hopkins+, 1998)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/352/131https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/352/131http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/352/131https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/352/131https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/352/131http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/352/131GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/352/131/tablea1 (1.4GHz source catalog in 13+38 XMM field)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/352/131/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/352/131/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/352/131/tablea1?GETtext/xml+votable180.050000true203.37137.932750.0055555555555555566/10484https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/352/131?format=asciiX-rayRadiodefaultJ/MNRAS/352/131/tablea11.4GHz source catalog in 13+38 XMM fieldrecnoRecord number assigned by the VizieR team.
