The impact of flickering variability and magnetisation on the dynamics, stability and morphology of radio-loud AGN jets

This project used relativistic magnetohydrodynamic simulations of AGN jets with varying power. Emissivities were estimated based on the strength of the magnetic field and are Doppler-boosted on a cell-by-cell basis.

Simulated radio images of a variable power, highly magnetised AGN jet simulation

This animation shows simulated radio images from our 2026 paper, showing simulated radio images from a variety of angles to the line of sight. The observer first "orbits" about the jet axis, before moving such that the jet points towards the observer and then away. Different timestamps from 3 Myr to 5 Myr are shown sequentially, with 0.25 Myr between each timestamp.

Simulated radio images of a constant power, highly magnetised AGN jet simulation

Constant power simulation. Different timestamps from 3 Myr to 5 Myr are shown sequentially, with 0.5 Myr between each timestamp.

Simulating radio emission from flickering AGN jets: travelling shocks and hotspot brightening

This project used relativistic hydrodynamic simulations of jets with varying power. Particle acceleration and emission were modelled using a Lagrangian particle approach.

Emissivity map for a flickering radio jet at 144 MHz.

This animation shows the evolution of the emissivity map with time from one line of sight (90 degrees to the jet direction). Travelling shocks move along the jet beam, with a greatly increased hotspot luminosity when they reach the jet head.
