Synchrotron filaments in radio galaxies: rarity, stability, and environmental influences from LOFAR and ROSAT observations
Geoffrey Ong'alo, Martin J. Hardcastle, Willice Obonyo +2
We present a systematic investigation of filamentary synchrotron structures in radio galaxies, using deep 144 MHz observations from the LOFAR Two-Metre Sky Survey (LoTSS) in combin…
MIGHTEE: The Host-Galaxy Associated Catalogue of the Radio Sources in MIGHTEE Continuum Data Release 1
C. L. Hale, J. Hamlett, I. H. Whittam +34
Radio continuum surveys provide samples of active galactic nuclei (AGN) and star forming galaxies (SFGs) to high redshifts, free of biases due to dust obscuration. However, radio d…
The DESI View of the Faint Radio Source Population in LoTSS DR2
M. I. Arnaudova, L. R. Holden, D. J. B. Smith +10
The faint radio-source population includes galaxies dominated by both star formation (SF) and active galactic nuclei (AGN), which are two key processes shaping galaxy evolution. To…
A simulation-based analytic model of radio galaxies II: self-consistent radiative losses
M. J. Hardcastle
The evolution of the radio properties of high-redshift radio-luminous active galactic nuclei is well known to be strongly affected by inverse-Compton losses which increase rapidly…
Radio Galaxies and Jet Duty Cycles
M. J. Hardcastle, C. Konar, S. Dutta +10
Radio-luminous active galactic nuclei, or radio galaxies, are the brightest population of objects in the extragalactic radio sky and will be seen in large numbers in essentially ev…
The ultra low-frequency spectral properties of bright extended radio galaxies in the 3CRR catalogue
J. M. Boxelaar, F. De Gasperin, M. J. Hardcastle +2
Context. Active galactic nuclei (AGN) jets are fundamental drivers of galaxy evolution, injecting kinetic energy into their environments. The large-scale morphology and spectral pr…
