aula 131

I will present results of fully general relativistic magnetohydrodynamic
(GRMHD) simulations of binary neutron star mergers performed by my group
in Trento. Thanks to the detection of GW170817 the new era of
multi-messenger astrophysics has finally started. That detection
provided us with evidence for the first time of the connection between
binary neutron star mergers and short gamma-ray bursts as well as other
electromagnetic signals, such as the predicted kilonova emission.
Numerical simulations of binary neutron stars have helped in the study
of the dynamics of these systems during the last phases of inspiral,
merger, and post-merger evolution. In this talk I will present results
of numerical simulations performed by my group in Trento and that
focused in particular on the effects that magnetic fields may have both
in powering short gamma-ray bursts and in affecting the gravitational
wave emission.
