    • Accretion mode versus radio morphology in the LOFAR Deep Fields 

      Mingo, B.; Croston, J. H.; Best, P. N.; Duncan, K. J.; Hardcastle, M. J.; Kondapally, R.; Prandoni, I.; Sabater, J.; Shimwell, T. W.; Williams, W. L.; Baldi, R. D.; Bonato, M.; Bondi, M.; Dabhade, P.; Gürkan, G.; Ineson, J.; Magliocchetti, M.; Miley, G.; Pierce, J. C. S.; Röttgering, H. J. A. (2022-02-16)
      Radio-loud active galaxies have two accretion modes [radiatively inefficient (RI) and radiatively efficient (RE)], with distinct optical and infrared signatures, and two jet dynamical behaviours, which in arcsec- to ...

    • The environments of radio-loud AGN from the LOFAR Two-Metre Sky Survey (LoTSS) 

      Croston, J. H.; Hardcastle, M. J.; Mingo, B.; Best, P. N.; Sabater, J.; Shimwell, T. W.; Williams, W. L.; Duncan, K. J.; Röttgering, H. J. A.; Brienza, M.; Gürkan, G.; Ineson, J.; Morabito, L. M.; Miley, G. K.; O'Sullivan, S. P.; Prandoni, I. (2018-10-10)
      An understanding of the relationship between radio-loud active galaxies and their large-scale environments is essential for realistic modelling of radio-galaxy evolution and environmental impact, for understanding AGN ...

    • 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 ...

    • A new method for finding and characterizing galaxy groups via low-frequency radio surveys 

      Croston, J. H.; Ineson, J.; Hardcastle, M. J.; Mingo, B. (2017-09-11)
      We describe a new method for identifying and characterizing the thermodynamic state of large samples of evolved galaxy groups at high redshifts using high-resolution, low-frequency radio surveys, such as those that will ...

    • Particle content, radio-galaxy morphology and jet power : all radio-loud AGN are not equal 

      Croston, J. H.; Ineson, J.; Hardcastle, M. J. (2018-05-11)
      Ongoing and future radio surveys aim to trace the evolution of black hole growth and feedback from active galactic nuclei (AGNs) throughout cosmic time; however, there remain major uncertainties in translating radio ...

    • 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 ...

    • Revisiting the Fanaroff-Riley dichotomy and radio-galaxy morphology with the LOFAR Two-Metre Sky Survey (LoTSS) 

      Mingo, B.; Croston, J. H.; Hardcastle, M. J.; Best, P. N.; Duncan, K. J.; Morganti, R.; Rottgering, H. J. A.; Sabater, J.; Shimwell, T. W.; Williams, W. L.; Brienza, M.; Gurkan, G.; Mahatma, V. H.; Morabito, L. K.; Prandoni, I.; Bondi, M.; Ineson, J.; Mooney, S. (2019-09-01)
      The relative positions of the high and low surface brightness regions of radio-loud active galaxies in the 3CR sample were found by Fanaroff and Riley to be correlated with their luminosity. We revisit this canonical ...

    • 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 ...
