Abstract

The first direct detection of gravitational waves was announced 5 years ago (about 1 graduate student generation).  The LIGO and Virgo Collaboration (which now includes KAGRA too) has recently updated their catalog of merging binaries of black holes and neutron stars: the catalog now contains a total of 50 events.In this talk I will give an overview of what gravitational waves are and how we observe them.  I will discuss the discoveries made over the past 5 years and how they help us learn about fundamental physics (tests of relativity; state of dense matter), astrophysics (origin of neutron star and black hole binaries; origin of certain elements), and cosmology.
