Binary neutron star merger simulations with the GRMHD code Spritz

In the new era of multi-messenger astrophysics, events such as binary neutron star mergers have come under the limelight in the astrophysics community. In order to probe the various physical mechanisms involved in such events, it is necessary to model these systems as accurately as possible and general relativistic magnetohydrodynamic (GRMHD) simulations play a fundamental role. In this talk, I will present our new GRMHD code called Spritz, discussing its salient features including the support for realistic microphysical equations of state, the implemented neutrino leakage scheme, the inclusion of higher order methods, as well as our new conservative-to-primitive variable recovery scheme. Then, I will discuss the on-going work and some of the results obtained with this new code in the context of BNS merger simulations.
