Black hole depiction

A black hole surrounded by an accretion disc of superheated gas. A powerful jet of particles is launched from the region near the black hole's pole, travelling at relativistic speeds (close to the speed of light).

Research Summary

My research focuses on black hole accretion and the formation of relativistic jets, particularly the physical processes occurring in the innermost regions of accretion flows and during powerful jet ejection events.

I am particularly interested in using millimetre-wavelength observations to probe these regions, where higher observing frequencies allow us to study jet evolution at earlier stages than traditional radio observations. By combining observational data with relativistic numerical modelling, I aim to investigate the dynamics, energetics and internal physics of jet ejections, and better understand the relationship between accretion and jet formation.

My broader research interests include high-energy astrophysics, relativistic accretion flows, astrophysical transients and the application of computational methods to understanding extreme astrophysical environments.
