One of the next great discoveries in astrophysics will be the ﬁrst detection of an event in both gravitational waves and photons. I investigate the most promising event for a joint detection: the merging of a neutron star with another neutron star or a black hole, thought to produce short gamma ray bursts. We investigate the possibility of sub-populations of short gamma-ray bursts by comparing the bursts observed by the Swift Burst Alert Telescope and the Fermi Gamma-ray Burst Monitor. We ﬁnd no evidence that these instruments are observing diﬀerent short gamma-ray bursts, allowing us to use the Swift redshift distribution for the population observed by the Fermi Gamma-ray Burst Monitor. I discuss expected rates, joint localizations, and prospects for joint science between Advanced LIGO and the Fermi Gamma-ray Burst Monitor. Additionally, I discuss the unexpected candidate GBM gamma-ray counterpart to the ﬁrst detection of gravitational waves, a binary black hole merger, the likelihood that these events are associated, and the possibility of short gamma-ray bursts arising from the merging of black holes.
