AGN with $P[1.4 GHz]>10^{23.5} W Hz^{-1} sr^{-1}$ are twice more likely to be found in clusters with respect to fainter sources (~38% vs ~15%), just as radio-selected AGN with stellar masses $M*>10^{11} M_\odot$ are twice more likely to be found in overdense environments with respect to objects of lower mass (~24% vs ~11%). 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% of the sources found as satellite galaxies have $M*<10^{11.3} M_\odot$, while ~100% of the AGN coinciding with a cluster central galaxy have $M*>10^{11} M_\odot$. No different location within the cluster is instead observed for AGN of various radio luminosities. Radio AGN which also emit in the MIR show a marked preference to be found as isolated galaxies (~70%) at variance with those also active in the X-ray which 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.STAMPAenArticle10.1093/mnras/sty13092-s2.0-85054618967000441282300072http://arxiv.org/abs/1805.06233v1https://academic.oup.com/mnras/article/478/3/3848/49988802018MNRAS.478.3848MFIS/05 - ASTRONOMIA E ASTROFISICA
