cds-question@unistra.frx-ray-sourcesradio-galaxiesredshiftedphotometryWith the goal of investigating the nature and the environment of the faint radio sources (at mJy level), here are presented results of X-ray identifications of Faint Imaging Radio Survey at Twenty centimetres (FIRST) in the 9deg^2^ Bootes field of the National Optical Astronomy Observatory (NOAO) Deep Wide Field Survey (NDWFS), using data from the Chandra XBootes survey. A total of 92 (10 per cent) FIRST radio sources are identified above the X-ray flux limit f_X_)(0.5-7)keV=8x10^-15^erg/s/cm^2^, and 79 optical counterparts are common to both the radio and X-ray sources. Spectroscopic identifications [obtained from the Sloan Digital Sky Survey (SDSS) survey] were available for 22 sources (27 per cent).2009MNRAS.396.2011Ehttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/396/2011CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/161/9 : X-ray survey of the NDWFS Bootes field (Kenter+, 2005)J/ApJ/641/140 : Optical counterparts in the NDWFS Bootes field (Brand+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/396/2011https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/396/2011http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/396/2011https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/396/2011https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/396/2011http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/396/2011GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/396/2011/table1 (Characterization of faint radio sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/396/2011/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/396/2011/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/396/2011/table1?GETtext/xml+votable180.050000true216.20541734.1624170.0055555555555555565/2286 2628 6/9148 9150-9151 9194 10501 10516-10518 105219.276497240453405e-25 9.276497240453405e-25https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/396/2011?format=asciiX-rayOpticalRadiodefaultJ/MNRAS/396/2011/table1Characterization of faint radio sourcesrecnoRecord number assigned by the VizieR team.
