Recent work has demonstrated fundamental differences between high- and low-excitation radio galaxies (HERGs and LERGs), and shown that they may have different relationships with their environments. In the Chandra Large Project ERA (Environments of Radio-loud AGN), we made the first systematic X-ray environmental study of the cluster environments of radio galaxies at a single epoch (z~0.5), and found tentative evidence for a correlation between radio luminosity and cluster X-ray luminosity. We also found that this relationship appeared to be driven by the LERG subpopulation. We have now repeated the analysis with a low-redshift sample (z~0.1), and found strong correlations between radio luminosity and environment richness and between radio luminosity and central density for the LERGs but not for the HERGs. These results are consistent with models in which the HERGs are fuelled from accretion discs maintained from local reservoirs of gas, while LERGs are fuelled more directly by gas ingested from the intracluster medium. Comparing the samples, we found that although the maximum environment richness of the HERG environments is similar in both samples, there are poorer HERG environments in the z~0.1 sample than in the z~0.5 sample. We have therefore tentative evidence of evolution of the HERG environments. We found no differences between the LERG subsamples for the two epochs, as would be expected if radio and cluster luminosities are related.2015MNRAS.453.2682Ihttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/453/2682CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/204/151 : Bright radio sources at 178 MHz (3CRR) (Laing R.A., 1983)J/MNRAS/216/173 : Bright extragalactic radio sources at 2.7 GHzJ/MNRAS/419/687 : Morphology of luminous radio-loud AGN (Ramos Almeida+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/453/2682https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/453/2682http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/453/2682https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/453/2682https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/453/2682http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/453/2682GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/453/2682/table1 (The z0.1 sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/453/2682/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/453/2682/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/453/2682/table1?GETtext/xml+votable180.050000true13.961041726.41036110.0055555555555555566/246 2227 2414 2866 4835 5311 5817 7005 7959 8555 8675 8705 9009 9443 9468 10355 10839 11408 11512 12241 13120 13564 13707 15045 16301 18065 18365 18683 19321 19432 19543 19935 20355 21588 23167 23469 27382 30140 31352 31509 32059 32394 34669 35434 36100 36595 39079 39087 39658 40777 42060 45823 46101 47636 48501https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/453/2682?format=asciiX-rayOpticalRadiodefaultJ/MNRAS/453/2682/table1The z0.1 samplez[0.017/0.195] Redshiftsrc.redshiftfloatrecnoRecord number assigned by the VizieR team.
