Gama-Ray Bursts (GRB) are short (up to few tens of seconds) and intense flashes of gamma-rays, appearing from random directions over the entire sky. The gamma-rays (and the later afterglow emission observed at other wavelenghts) are associated to shock accelerated particles within relativistic narrow jets of plasma. The jets are created by the collapse of very massive stars (more than 50 times the mass of the Sun) or the merging of two compact objects (e.g. two neutron stars).

SVOM (Space based Variable astronomical Object Monitor) is a Sino-French mission developed in collaboration by the French Space Agency (CNES) and the Chinese Academy of Science (CAS) and the Chinese National Space Administration (CNSA). It is planned for launch early 2023 for a nominal mission lifetime of three years.

It will carry on-board four instruments among which the Micro-channel X-ray Telescope (MXT), a focusing X-ray telescope with a field of view of about 1°x1°, sensitive in the 0.2-10 keV energy range. The successful PHD candidate will be part of the MXT science team and be in charge of analyzing MXT data, since the very beginning of the SVOM mission. X-ray afterglow data will be coupled to the multi wavelength data in order to build a clear phenomenological picture of the SVOM GRBs, and to understand GRB progenitors and radiation processes.
