Neutron Star Binary Merger GW170817

Presented by Huaiyu Duan (UNM)

On 17 August, 2017, the Advanced LIGO/Virgo network detected the first gravitational wave event GW170817 resulting from a binary neutron star merger. A weak short gamma ray burst was independently detected by the Fermi Gamma-Ray Burst Monitor from the same sky location. Later several groups were able to identify an optical counter part of GW170817 in the galaxy NGC 4993 at a distance of about 40 Mpc. In the following days multiple ground- and space-based telescopes were utilized to track this transient across the EM spectrum.

I will lead a discussion on this discovery which is of great importance to both astrophysics and nuclear physics. The details of the discovery can be found in recent publications in PRL, ApJ and Nature:
