Description

Constraining the equation of state (EoS) of cold dense matter in neutron stars (NS) is a major science goal for observing programmes conducted with X-ray,
radio, and gravitational wave telescopes. In this talk we demonstrate how to combine gravitational-wave and electromagnetic observations in order to solve
the relativistic inverse stellar problem, i.e. to reconstruct the main features of the EoS. Using a full Bayesian analysis, we apply this approach to the
data obtained by the LIGO/Virgo collaboration for the binary neutron star detection GW170817, setting new constraints on the parameters that characterise
the behaviour of matter at supra-nuclear densities.
