"GW170817: A neutron star merger observed in gravitational and electromagnetic waves."

On August 17, the Laser Interferometer Gravitational-wave Observatory (LIGO) and the Virgo detector observed the ripples in space from a neutron star merger. Two second later NASA's Fermi Gamma Ray Burst Monitor detected a flash of gamma rays from the collision. LIGO and Virgo localized the source to a 30 square degree patch of the sky in the constellation Hydra and, twelve hours later, an optical counterpart was detected. I will discuss the detection of the neutron star merger, the associated kilonova, and the implications that this multi-messenger observation has for our understanding of the universe.
