Simulating radio emission from flickering AGN jets: travelling shocks and hotspot brightening
Published in Monthly Notices of the Royal Astronomical Society, 2026
We investigate the impact of flickering variability in jet power on the luminosity and morphology of radio galaxies. We use a Lagrangian particle method together with relativistic hydrodynamics simulations using the PLUTO code to track the evolution of electron spectra through particle acceleration at shocks and cooling processes.

The impact of flickering variability and magnetisation on the dynamics, stability and morphology of radio-loud AGN jets
The physics governing the morphology of radio-loud AGN jets is not fully understood. We investigate how magnetization, flickering jet power and their interplay affects the morphology of radio galaxies. We present a grid of relativistic magnetohydrodynamic simulations using the PLUTO code covering constant and variable jets with two levels of magnetisation.
