Title:  What can gravitational wave detectors tell us about nuclear and particle physics?

Speaker:  Peter Shawhan (U. of Maryland)

Abstract:  LIGO and other large gravitational-wave detectors have now detected signals from over 100 merging binary black hole systems, and from a few merging binary neutron star systems.  Along with testing the fundamental physics of gravity (GR), I will point out the ways in which these observations are providing information about nuclear and particle astrophysics.  I will also summarize searches for ultralight boson states that could be revealed through distinctive gravitational wave emission or through direct interaction with gravitational-wave detectors.
