The Laser Interferometer Gravitational-wave Observatory (LIGO) detectors sense gravitational waves; minuscule fluctuations in space-time from the most extreme phenomena in the Universe. The recent detection of gravitational waves from a neutron star merger and an associated electromagnetic counterpart was a breakthrough in multi-messenger astronomy. This discovery confirmed the association between neutron star mergers and short gamma-ray bursts (sGRBs), confirmed these events as major producers of heavy elements in the Universe, and yielded new insight into the physical engine driving sGRBs. Future gravitational wave observations have the potential to provide critical insight into key open questions in astrophysics, including the distribution of massive stellar remnants in the Universe, massive stellar evolution in binaries, galaxy formation, and the explosion mechanism of core-collapse supernovae.
