Radio-loud active calactic nucleus: is there a link between luminosity and cluster environment?. The Astrophysical Journal , 770 (136): 1-140004-637xhttp://hdl.handle.net/10566/3110http://dx.doi.org/10.1088/0004-637X/770/2/136We present here the first results from the Chandra ERA (Environments of Radio-loud AGN) Large Project, characterizing the cluster environments of a sample of 26 radio-loud active galactic nuclei (AGNs) at z ∼ 0.5 that covers three decades of radio luminosity. This is the first systematic X-ray environmental study at a single epoch, and has allowed us to examine the relationship between radio luminosity and cluster environment without the problems ofMalmquist bias.We have found a weak correlation between radio luminosity and host cluster X-ray luminosity, as well as tentative evidence that this correlation is driven by the subpopulation of low-excitation radio galaxies, with high-excitation radio galaxies showing no significant correlation. The considerable scatter in the environments may be indicative of complex relationships not currently included in feedback models.enThis is the author-version of the article published online at: http://dx.doi.org/10.1088/0004-637X/770/2/136GalaxiesActive – galaxiesJetsArticle
