The link between accretion mode and environment in radio-loud active galaxies
Ineson, J.; Croston, J. H.; Hardcastle, M.J.; Kraft, R.P.; Evans, D. A.; Jarvis, M.J. (2015-11-01)The interactions between radio-loud AGN and their environments play an important rôle in galaxy and cluster evolution. Recent work has demonstrated fundamental differences between high- and low-excitation radio galaxies ... -
Radio-Loud Active Galactic Nucleus : is there a link between luminosity and cluster environment?
Ineson, J.; Croston, J.H.; Hardcastle, M.J.; Kraft, R.P.; Evans, D. A.; Jarvis, M.J. (2013-06-20)We 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 similar to 0.5 ... -
An X-ray survey of the 2 Jy sample - II. X-ray emission from extended structures
Mingo, B.; Hardcastle, M. J.; Ineson, J.; Mahatma, V.; Croston, J. H.; Dicken, D.; Evans, D. A.; Morganti, R.; Tadhunter, C.N. (2017-09-21)The 2 Jy sample is a survey of radio galaxies with flux densities above 2 Jy at 2.7 GHz. As part of our ongoing work on the southern subset of 2 Jy sources, in paper I of this series we analysed the X-ray cores of the ... -
An X-ray survey of the 2 Jy sample-I : Is there an accretion mode dichotomy in radio-loud AGN?
Mingo, B.; Hardcastle, M.J.; Croston, J.H.; Dicken, D.; Evans, D. A.; Morganti, R.; Tadhunter, C. (2014-05-01)We carry out a systematic study of the X-ray emission from the active nuclei of the 0.02 < z< 0.7 2 Jy sample, using Chandra and XMM-Newton observations.We combine our results with those from mid-infrared, optical emission-line ...
