Interpreting the multi-messenger picture drawn by compact binary mergers

Tim Dietrich
Uni Potsdam

Neutron stars are among the most compact objects in the Universe, and the detection of gravitational waves and electromagnetic signals from the merger of two neutron stars has been a revolution. Essential for an accurate interpretation of binary neutron star mergers are reliable models describing the last stages of their coalescence. We show how numerical-relativity simulation can be used to derive such theoretical models for the gravitational-wave and electromagnetic signatures. Finally, we employ these models together with nuclear-physics computations and experimental data to measure the equation of state of neutron stars, and to provide new constraints on the Hubble constant.
