How loud are Neutron Star Mergers?

Our new paper led by Sebastiano Bernuzzi is out in Physical Review D! The paper is about a large set of neutron star merger simulations, using three different finite-temperature nuclear equation of state and binary parameters motivated by the galactic double neutron star population. Our focus was on how "loud" these mergers are in gravitational waves and what phase of their evolution is the "loudest".

Also exciting: We are providing open access to the gravitational waveforms extracted from our merger simulations. For details, see: Here is the money plot from the paper:

This figure shows that most of the gravitational wave energy in the entire history of a coalescing neutron star binary is actually emitted in the first ~10 ms after merger
