cds-question@unistra.frradio-sourcesgalaxiesphotometryWe explore the environments of two radio galaxies at z~1.5, 7C 1751+6809 and 7C 1756+6520, using deep optical and near-infrared imaging. Our data cover 15x15arcmin^2^ fields around the radio galaxies. We develop and apply BzK color criteria to select cluster member candidates around the radio galaxies and find no evidence of an overdensity of red galaxies within 2Mpc of 7C 1751+6809. In contrast, 7C 1756+6520 shows a significant overdensity of red galaxies within 2Mpc of the radio galaxy, by a factor of 3.1+/-0.8 relative to the four MUSYC fields. At small separation (r<6"), this radio galaxy also has one z>1.4 evolved galaxy candidate, one z>1.4 star-forming galaxy candidate, and an AGN candidate (at indeterminate redshift).2009A&A...507..131Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/507/131CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/507/131https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/507/131http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/507/131https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/507/131https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/507/131http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/507/131GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/507/131/pBzKs (Combined table from original tables)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/507/131/pBzKs?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/507/131/pBzKs?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/507/131/pBzKs?GETtext/xml+votable180.050000true269.44365.23180560.0055555555555555566/10237 10239 11613 116157.952274030004205e-20 1.7798557115773645e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/507/131?format=asciiRadioOpticaldefaultJ/A+A/507/131/pBzKsCombined table from original tablesrecnoRecord number assigned by the VizieR team.
