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 Merging Galaxy Cluster Environment Affects the Morphology of Radio-AGN
Mary Rickel, Emily Moravec, Yjan A. Gordon +4
It has previously been found that the galaxy cluster environment can affect the fueling and evolution of Active Galactic Nuclei (AGN). This work examines the effect of the merging…
Radio AGN selection in LoTSS DR2
M. J. Hardcastle, J. C. S. Pierce, K. J. Duncan +6
The wide-area component of the LOFAR Two-Metre Sky Survey (LoTSS) is currently the largest radio survey ever carried out, and a large fraction of the 4.5 million radio sources it c…
The nature of HERGs and LERGs in LoTSS DR2 a morphological perspective
J. Chilufya, M. J. Hardcastle, J. C. S. Pierce +4
We present the largest visually selected sample of extended (60 arcsec) radio-loud active galactic nuclei (RLAGN) to date, based on the LOw-Frequency Array Two-Metre Sky Survey…
Limits and challenges of the detection of cluster-scale diffuse radio emission at high redshift: The Massive and Distant Clusters of WISE Survey (MaDCoWS) in LoTSS-DR2
G. Di Gennaro, M. Brüggen, E. Moravec +14
Diffuse radio emission in galaxy clusters is a tracer of ultra-relativistic particles and G-level magnetic fields, and is thought to be triggered by cluster merger events. In t…
