Observational Biases and Improved Modelling of Off-axis Relativistic Jets
A. J. Cooper, A. P. Scott, L. Rhodes +8
Relativistic Doppler boosting significantly affects the observed emission of astrophysical jets resulting in observational biases. In this work we investigate the observational bia…

Simulating radio emission from flickering AGN jets: travelling shocks and hotspot brightening
Emma L. Elley, James H. Matthews, Dipanjan Mukherjee +1
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…

Blast waves and reverse shocks: from ultra-relativistic GRBs to moderately relativistic X-ray binaries
James H. Matthews, Alex J. Cooper, Lauren Rhodes +8
Blast wave models are commonly used to model relativistic outflows from ultra-relativistic gamma-ray bursts (GRBs), but are also applied to lower Lorentz factor ejections from X-ra…
