cds-question@unistra.frgalaxy-clustersquasarsinfrared-photometryvisible-astronomyphotometryWe previously reported a significant clustering of red galaxies (R-K=3.56) around the radio-loud quasar B2 1335+28 at z=1.086. In this paper, we establish the existence of a rich cluster at the quasar redshift and study the properties of the cluster galaxies through further detailed analysis of the photometric data. We also list the positions, K-band magnitudes, and colors of all K<19 objects. The near-infrared (NIR) K-band imaging data presented in earlier paper, together with some additional K-band data, is newly analyzed to study the extent of the clustering of the red galaxies. We also constrain the cluster redshift by applying a robust photometric redshift estimator and find a strong peak around z=1.1. The color distribution of the galaxies in the cluster is quite broad, and the fraction of blue galaxies (70%) is much larger than in intermediate-redshift clusters.2000ApJ...528..123Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/528/123CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/528/123https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/528/123http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/528/123https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/528/123https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/528/123http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/528/123GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/528/123/table1 (K-selected object catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/528/123/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/528/123/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/528/123/table1?GETtext/xml+votable180.050000true204.51321528.08757220.0055555555555555566/10295 10338https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/528/123?format=asciiOpticalInfrareddefaultJ/ApJ/528/123/table1K-selected object catalogrecnoRecord number assigned by the VizieR team.
