Description
We discuss how one can use numerical-relativity simulations to derive gravitational-wave and electromagnetic models describing the binary neutron star coalescence. Such models can be used to perform multi-messenger studies in which the gravitational wave signals GW170817, GW190425, and the observed electromagnetic signals AT2017gfo and GRB170817A are analyzed. We combine the obtained information with an analysis of X-ray and radio observations of single neutron stars, nuclear theory computations, and information from heavy-ion collisions. In general, nuclear physics - multi-messenger astronomy studies provide new constraints on the neutron-star equation of state and the Hubble constant.
