cds-question@unistra.frgalaxy-clustersactive-galactic-nucleix-ray-sourcesinfrared-sourcesWe aim to study the effect of environment on the presence and fuelling of active galactic nuclei (AGNs) in massive galaxy clusters. We explore the use of different AGN detection techniques with the goal of selecting AGN across a broad range of luminosities, AGN/host galaxy flux ratios and obscuration levels. From a sample of 12 galaxy clusters at redshifts 0.5<z<0.9, we identify AGN candidates using optical variability from multi-epoch Hubble Space Telescope imaging, X-ray point sources in Chandra images and mid-infrared (IR) spectral energy distribution power-law fits through the Spitzer Infrared Array Camera channels. We find 178 optical variables, 74 X-ray point sources and 64 IR power-law sources, resulting in an average of ~25 AGN per cluster.2012MNRAS.425.1215Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/425/1215CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/425/1215https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/425/1215http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/425/1215https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/425/1215https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/425/1215http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/425/1215GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/425/1215/table9 (IR power-law galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/425/1215/table9?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/425/1215/table9?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/425/1215/table9?GETtext/xml+votable180.050000true28.18225528-13.983726390.005555555555555556Cone search capability for table J/MNRAS/425/1215/clusters (Cluster observations (table1), properties (table2) and X-ray observations (table6))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/425/1215/clusters?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/425/1215/clusters?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/425/1215/clusters?GETtext/xml+votable180.050000true28.1791667-13.95555560.005555555555555556Cone search capability for table J/MNRAS/425/1215/table4 (Optical variables: two epochs)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/425/1215/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/425/1215/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/425/1215/table4?GETtext/xml+votable180.050000true177.3912547222.374179720.005555555555555556Cone search capability for table J/MNRAS/425/1215/table5 (Optical variables: three epochs)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/425/1215/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/425/1215/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/425/1215/table5?GETtext/xml+votable180.050000true44.30556083-23.438953060.005555555555555556Cone search capability for table J/MNRAS/425/1215/table7 (X-ray point sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/425/1215/table7?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/425/1215/table7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/425/1215/table7?GETtext/xml+votable180.050000true28.18226-13.983743890.0055555555555555566/4512 5733 6383 6539 8915 8921 17472 18475 22915 27009 28448 28535 360822.0616683193919197e-20 6.185923063528282e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/425/1215?format=asciiX-rayInfrareddefaultJ/MNRAS/425/1215/table9IR power-law galaxiese_IRAC1rms uncertainty on IRAC1uJystat.errorfloatrecnoRecord number assigned by the VizieR team.
