Illuminating the Dark Universe with Gravitational Waves

Abstract

For centuries, we have explored the Universe and discovered novel astrophysical sources and phenomena through the observation of electromagnetic waves. In 2015, we observed the first gravitational wave passing through the Earth produced by the merger of two black holes. Since then, a few hundred gravitational waves have been detected, including the gravitational signal produced by the coalescence of two neutron stars, accompanied by a plethora of electromagnetic counterparts observed around the world. In this talk, I will highlight the theoretical work underpinning these observations and review the main results in astrophysics, cosmology and fundamental physics. I will then discuss the discovery potential of future observatories in space and on the ground.
