A new perspective onto the Universe in the era of multi-messenger astrophysics

In the past three years, the LIGO and Virgo gravitational wave (GW) detectors have announced the discovery of ten binary black hole mergers as well as the the first binary neutron star merger, dubbed GW170817. The observations of both gravitational wave and electromagnetic (EM) radiation from this one binary neutron star merger, GW170817, have instigated a rapidly and exploding new era of multi-messenger physics. Although only a single event, its GW+EM characterization have offered us a new perspective onto the Universe enabling critical insights into diverse fields from gravity, high-energy astrophysics, nuclear physics, to cosmology.

In this talk, I will give a brief overview of the GW discovery and EM follow-up of this event, and then discuss how to place compact object mergers in their full cosmological and astrophysical context using joint GW+EM measurements. I will conclude by discussing the lessons that we are learning from this one event and the remarkable opportunities and challenges that are emerging in this now observationally-driven and fast-paced field as we move from the discovery era to one of precision physics in the next decade.

Drinks after the colloquium will be served at the Academische Kwartier.
