Eruptions, disruptions and explosions in our Universe!!

My research focuses on the  biggest explosions that occur in our Universe: Supernovae and Gamma-Ray Bursts. Both phenomena signal the catastrophic death of stars, leading to the birth of exotic compact objects like neutron stars and black holes. Investigating the high-energy  (UV, to X-rays and gamma-rays) properties of these explosions, I want to understand the physical processes that cause such a dramatic energy release in a matter of seconds!

Working field: 
High-energy astrophysics

Wave-length: 
UV, X-Rays, gamma-rays
objects of interest:
Gamma-ray bursts
Engine driven Supernovae
Type Ia SNe
Super-luminous SNe
Tidal disruption events
