Host galaxies of long gamma-ray bursts in the Millennium Simulation

In this work, we investigate the nature of the host galaxies of long gamma-ray bursts (LGRBs) using a galaxy catalogue constructed from the Millennium Simulation. We developed an LGRB synthetic model based on the hypothesis that these events originate at the end of the life of massive stars followin...
