Abstract:Using data from 289 numerical relativity simulations of merging binary neutron stars, we identify, for the first time, a robust quasi-universal relation connecting the postmerger peak gravitationalwave frequency and the value of the density at the center of the maximum mass nonrotating neutron star. This relation offers a new possibility for precision equation-of-state constraints with nextgeneration ground-based gravitational-wave interferometers. Mock Einstein Telescope observations of fiducial events indica… Show more
