cds-question@unistra.frredshiftedgalaxy-clustersspectroscopysurveysinfrared-photometryWe have identified 335 galaxy cluster and group candidates, 106 of which are at z>1, using a 4.5um-selected sample of objects from a 7.25deg^2^ region in the Spitzer Infrared Array Camera (IRAC) Shallow Survey. Clusters were identified as three-dimensional overdensities using a wavelet algorithm, based on photometric redshift probability distributions derived from IRAC and NOAO Deep Wide-Field Survey data. We estimate only ~10% of the detections are spurious. To date 12 of the z>1 candidates have been confirmed spectroscopically, at redshifts from 1.06 to 1.41. Velocity dispersions of ~750km/s for two of these argue for total cluster masses well above 10^14^M_{sun}_, as does the mass estimated from the rest-frame near-infrared stellar luminosity. Although not selected to contain a red sequence, some evidence for red sequences is present in the spectroscopically confirmed clusters, and brighter galaxies are systematically redder than the mean galaxy color in clusters at all redshifts.2008ApJ...684..905Ehttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/684/905CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/442/841 : High-redshift galaxy clusters (Olsen+, 2005)http://www.noao.edu/noao/noaodeep : NOAO Deep images data archive home pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/684/905https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/684/905http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/684/905https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/684/905https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/684/905http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/684/905GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/684/905/table1 (z>1 ISCS clusters with spectroscopic confirmation)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/684/905/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/684/905/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/684/905/table1?GETtext/xml+votable180.050000true218.543208333.471750.005555555555555556Cone search capability for table J/ApJ/684/905/table3 (z>1 spectroscopic cluster members)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/684/905/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/684/905/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/684/905/table3?GETtext/xml+votable180.050000true218.532083333.40944440.0055555555555555566/9147 9149 9150 10512 10513 10516 105173.9193497546148093e-20 4.923046907857898e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/684/905?format=asciiOpticalInfrareddefaultJ/ApJ/684/905/table1z>1 ISCS clusters with spectroscopic confirmationrecnoRecord number assigned by the VizieR team.
