Title: Gravitational wave physics and black hole ringdown 

The detection of gravitational waves has revealed an invisible side of the Universe. Observations of orbiting and merging black holes allow us to test our understanding of these exotic objects, their violent merger, and the theory of general relativity. Meanwhile, observations of binary neutron stars inform us about matter at densities and temperatures out of reach of terrestrial experiments. I will give an overview of the gravitational wave detections made so far by the LIGO and Virgo collaborations, and discuss what we have learned from these observations. I will also highlight current efforts to observe and test the predicted ``ringdown'' of black holes, which provides an exciting avenue to search for new physics.
