Title: Equation of state of dense matter from multi-messenger observations of neutron stars

Abstract: The first observation of the gravitational wave signal from the inspiral phase of the binary neutron star merger GW170817 allowed robust constraints on the equation of state (EOS) from gravitational wave tidal signals. In addition, using X-ray missions, it is possible to measure the masses and radii of pulsar-like objects, which can add information on the dense matter EOS. I will introduce our related works and constrain the EOS as well as hadron-quark phase transition parameters from the multi-messenger observations.
