Seeing and Hearing the Universe at the Same Time

Earlier this year, the Laser Interferometer Gravitational-Wave Observatory (LIGO) was awarded the Nobel Prize in Physics for the detection of merging black holes by gravitational waves. Although this was an amazing triumph, black hole mergers do not emit light and are therefore invisible to telescopes. Neutron star mergers, however, have long been expected to produce both light and gravitational waves, so the detection of these events has been eagerly anticipated. Following the first ever detected gravitational waves from neutron stars on August 17, 2017, our team at the Carnegie Observatories, in collaboration with UC Santa Cruz, were the first to discover the optical counterpart. I will describe this incredible discovery, the data that was taken over the following weeks, and the implication for the origin of gold and other heavy elements in our Universe.
