Research
High-energy astrophysics deals with systems in which matter is pushed to extreme conditions, including strong gravitational fields, relativistic speeds, and temperatures of millions of degrees. These conditions arise naturally around compact objects like black holes, where the energy released can power bright electromagnetic flares and generate gravitational waves. Thanks to a new generation of dedicated observatories, such signals are now being detected at an unprecedented rate, offering a direct view of these phenomena. By confronting theory with observations, we can use these systems as natural laboratories to address fundamental questions in astrophysics, from the physical processes operating near black holes to the properties and distribution of these objects across the Universe.
Conducted alongside a group of postdoctoral fellows and PhD students, my research investigates the physics governing these high-energy systems through a combination of analytical techniques and numerical simulations, involving hydrodynamics, radiative transfer, magnetic fields and general relativity. The aim is to build the theoretical framework needed to optimally exploit observations, in order to unlock the full scientific potential of these phenomena. At present, my work primarily focuses on processes taking place in galactic nuclei, specifically tidal disruption events, quasi-periodic eruptions, and compact objects embedded in accretion discs.
A central part of this research is my ERC Starting Grant project “Unleash-TDEs”, which aims to develop end-to-end simulations of tidal disruption events to uncover the physical processes that generate their electromagnetic emission. This work will help maximise the scientific return from current and upcoming observations, particularly those from the Rubin Observatory.
