Title : Gamma-ray bursts detected by SVOM : unique probes for the exploration of galaxies and stellar evolution
Team : ASTRE
Supervisor : Susanna Vergani
Gamma-Ray Bursts (GRBs) are the most extreme explosions in the Universe, detected by satellites through sudden bursts of gamma-ray photons.
They originate from two main mechanisms : the collapse of massive stars forming accreting black holes (long GRBs), and the merger of compact objects like neutron stars (short GRBs).
Following detection, afterglow emission can last from days to months. Due to their brightness, GRBs serve as background beacons to study galaxies and star formation at high redshifts.
This PhD aims to use SVOM-detected GRBs to probe galaxy evolution. A major component involves rapid response and follow-up observation coordination, especially with ESO’s SOXS and VLT instruments.
