Accretion mode versus radio morphology in the LOFAR Deep Fields
B. Mingo, J. H. Croston, P. N. Best +17
Radio-loud active galaxies have two accretion modes [radiatively inefficient (RI) and radiatively efficient (RE)], with distinct optical and infrared signatures, and two jet dynami…
Investigating the spectral age problem with powerful radio galaxies
Vijay H. Mahatma, Martin J. Hardcastle, Judith H. Croston +3
The 'spectral age problem' is our systematic inability to reconcile the maximum cooling time of radiating electrons in the lobes of a radio galaxy with its age as modelled by the d…
Revisiting the Fanaroff-Riley dichotomy and radio-galaxy morphology with the LOFAR Two-Metre Sky Survey (LoTSS)
B. Mingo, J. H. Croston, M. J. Hardcastle +15
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 l…
Unveiling the 100 pc scale nuclear radio structure of NGC 6217 with e-MERLIN and the VLA
David R. A. Williams, Ian M. McHardy, Ranieri D. Baldi +13
We present high-sensitivity 1.51 GHz e-MERLIN radio images of the nearby galaxy NGC 6217. We resolve the compact radio source at the centre of NGC 6217 for the first time, finding…
The environments of radio-loud AGN from the LOFAR Two-Metre Sky Survey (LoTSS)
J. H. Croston, M. J. Hardcastle, B. Mingo +13
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 enviro…
Particle content, radio-galaxy morphology and jet power: all radio-loud AGN are not equal
J. H. Croston, J. Ineson, M. J. Hardcastle
Ongoing and future radio surveys aim to trace the evolution of black hole growth and feedback from active galactic nuclei (AGN) throughout cosmic time; however, there remain major…
An X-ray survey of the 2Jy sample. II: X-ray emission from extended structures
B. Mingo, M. J. Hardcastle, J. Ineson +6
The 2Jy 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 2Jy sources, in paper I of this series…
A new method for finding and characterizing galaxy groups via low-frequency radio surveys
J. H. Croston, J. Ineson, M. J. Hardcastle +1
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…
A representative survey of the dynamics and energetics of FRII radio galaxies
Judith Ineson, Judith H. Croston, Martin J. Hardcastle +1
We report the first large, systematic study of the dynamics and energetics of a representative sample of FRII radio galaxies with well-characterized group/cluster environments. We…
FR II radio galaxies at low frequencies I: morphology, magnetic field strength and energetics
Jeremy J. Harwood, Judith H. Croston, Huib T. Intema +14
Due to their steep spectra, low-frequency observations of FR II radio galaxies potentially provide key insights in to the morphology, energetics and spectrum of these powerful radi…
The link between accretion mode and environment in radio-loud active galaxies
Judith Ineson, Judith H. Croston, Martin J. Hardcastle +3
The interactions between radio-loud AGN and their environments play an important role in galaxy and cluster evolution. Recent work has demonstrated fundamental differences between…
The cluster environments of radio-loud AGN
Judith Ineson, Judith Croston, Martin Hardcastle +3
Radio-loud AGN play an important rôle in galaxy evolution. We need to understand their properties, and the processes that affect their behaviour in order to model galaxy formation…
