Dense Matter and Neutron Stars

PFC Major Activity 3 | The announcement on 17 August 2017 by LIGO and Virgo of the detection of gravitational waves from a binary neutron star merger, followed by the observation of electromagnetic signals from the associated kilonova as well as a short-duration gamma-ray burst, ushered in a new era of multi-messenger astrophysics and cosmology. In combination with observations of cold neutron stars of nearly two solar masses by Shapiro delay, and of “black-widow” systems hinting of even higher masses, the observations are placing important new constraints on the equation of state of nuclear matter. Current and anticipated observations provide unprecedented opportunities to probe nuclear matter at densities and isospins not otherwise reachable, and to relate its properties to those we measure in laboratory nuclei.
