Equation-of-state measurements based on joint multimessenger data

Our knowledge about dense matter explored in the cores of neutron stars remains limited, but fortunately, the detections of gravitational waves emitted from the merger of neutron stars and the corresponding electromagnetic signals provide a new way of studying supranuclear-dense material. Making use of the strength of multi-messenger astronomy, one can combine the information obtained from gravitational-wave observations, the electromagnetic counterparts of merging neutron stars with the information provided by NICER, radio pulsar observations, and heavy-ion collision experiments to derive new constraints on the neutron-star equation. As an outlook, we will use our obtained knowledge from previous observations, to anticipate how the next generation of observatories will help us to improve our knowledge about the supranuclear-dense equation of state.
