Imploding Remnants: detection bias against AGNs in massive clusters
Ross J. Turner, Georgia S. C. Stewart
We propose that an observed scarcity of remnant lobed AGNs in dense clusters results from a peculiarity in their dynamics upon the cessation of jet activity: a rapid `implosion' of…
CosmoDRAGoN II: Remnant Radio Galaxies in Group and Cluster Environments
Georgia S. C. Stewart, Stanislav S. Shabala, Ross J. Turner +5
Radio galaxy remnants are a rare subset of the radio-loud active galactic nuclei (RLAGN) population, representing the quiescent phase in the RLAGN lifecycle. Despite their observed…
The origin of the spectral versus dynamical age discrepancy in radio galaxies
Larissa Jerrim, Stas Shabala, Ross Turner +4
We investigate the effect of turbulent magnetic fields on the observed spectral properties of synchrotron radio emission in large-scale radio galaxy lobes. We use three-dimensional…
BRAiSE: synthetic polarisation in RMHD AGN jet simulations
Larissa Jerrim, Stas Shabala, Patrick Yates-Jones +4
We present a new method to calculate the polarised synchrotron emission of radio AGN sources using magnetic field information from 3-dimensional relativistic magnetohydrodynamical…
