Talk Title:  “Welcome to the Gravitational-wave Revolution”

Abstract:

The gravitational-wave detections by LIGO and Virgo in the past three years have already revealed breakthrough insights into the high energy cosmos.  Among the new knowledge revealed these detections— black holes can form in binary systems, binary black hole mergers seed the formation of more massive black holes, binary neutron star mergers produce gamma ray bursts, the heaviest elements in the periodic table likely come from the collision of two neutron stars, the radii of neutron stars can be constrained by gravitational-wave emissions, and the Hubble constant can be measured using gravitational-wave sources as standard sirens.

In this talk, I’ll give an overview of gravitational wave detectors, discuss some of the most interesting results to come out of the past two observing runs of the Advanced LIGO and Advanced Virgo detectors, and talk about where gravitational-wave astrophysics is going in the next decade and beyond.
