cds-question@unistra.fractive-galactic-nucleiradio-sourcesredshiftedWe study the environmental properties of z<=1.2 radio-selected active galactic nuclei (AGNs) belonging to the ~2deg^2^ of the COSMOS field, finding that about 20 per cent of them appear within overdense structures. AGNs with P_1.4GHz_>10^23.5^W/Hz/sr are twice more likely to be found in clusters with respect to fainter sources (~38 per cent vs ~15 per cent), just as radio-selected AGNs with stellar masses M_*_>10^11^M_{sun}_ are twice more likely to be found in overdense environments with respect to objects of lower mass (~24 per cent vs ~11 per cent). Comparisons with galaxy samples further suggest that radio-selected AGN of large stellar mass tend to avoid underdense environments more than normal galaxies with the same stellar content. Stellar masses also seem to determine the location of radio-active AGN within clusters: ~100 per cent of the sources found as satellite galaxies have M_*_<10^11.3^M_{sun}_, while ~100 per cent of the AGNs coinciding with a cluster central galaxy have M_*_>10^11^M_{sun}_. No different location within the cluster is instead observed for AGN of various radio luminosities. Radio AGN, which also emit in the Mid-Infrared show a marked preference to be found as isolated galaxies (~70 per cent) at variance with those also active in the X-ray that all seem to reside within overdensities. What emerges from our work is a scenario whereby physical processes on sub-pc and kpc scales (e.g. emission, respectively, related to the AGN and to star formation) are strongly interconnected with the large-scale environment of the AGN itself.2018MNRAS.478.3848Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/478/3848CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/532/A90 : PACS Evolutionary Probe (PEP-DR1) catalogs (Lutz+, 2011)J/ApJS/224/24 : The COSMOS2015 catalog (Laigle+, 2016)J/ApJ/837/16 : Cosmic web of galaxies in the COSMOS field (Darvish+, 2017)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/478/3848https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/478/3848http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/478/3848https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/478/3848https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/478/3848http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/478/3848GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/478/3848/table2 (Properties of the considered sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/478/3848/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/478/3848/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/478/3848/table2?GETtext/xml+votable180.050000true149.41922.02920.0055555555555555565/6814 6/27245 27247 273449.276497240453405e-25 1.9864425968556103e-21https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/478/3848?format=asciiRadiodefaultJ/MNRAS/478/3848/table2Properties of the considered sampleSimbadSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
