Description
At the dawn of multi-messenger astrophysics with gravitational wave sources, numerical relativity simulations of compact binary mergers involving black holes and neutron stars play, more than ever, a central role. An accurate representation of these systems requires solving Einstein’s equations on dynamical spacetimes, coupled with the general relativistic magnetohydrodynamic (GRMHD) equations. To face this challenge, we developed a new GRMHD code, named Spritz, capable of accurately evolving the magnetic field preserving its divergence-free condition, dealing with temperature and composition dependent equations of state, and taking into account neutrino radiation. In this talk, I will present the key features of this code and a range of possible applications, including in particular binary neutron star merger simulations.
