On August 17, 2017, a LIGO/VIRGO gravitational wave event and a Fermi Gamma Ray Burst Monitor (GBM) trigger occurred two seconds apart. The near-simultaneous observation of a short gamma ray burst and gravitational waves from a binary neutron star merger place strong limits on cosmological gravity and teach us new things about gamma ray and neutron star astrophysics. In this practice qual talk, I will explain the instrumentation of Fermi-GBM, give a description of GW/EM170817, and talk about its implications.
