"Gravitational Waves as a Probe of Fundamental Physics and Astrophysics"


Kent Yagi , UVA-Department of Physics
[Host: Despina Louca]
ABSTRACT:

Recent observations of black holes and neutron stars through gravitational waves allow us to explore the novel strong-gravity and extreme-density regime. In this talk, I will explain how we can use gravitational waves from binary black hole mergers to probe gravitational physics and those from binary neutron star mergers to study nuclear physics. For the former, I will focus on a theory beyond General Relativity motivated by string theory while for the latter, I will investigate the presence of solid quark cores inside neutron stars. I will also comment on how we can use gravitational waves from binary white dwarfs, expected to be detected with future space-based detectors, to learn astrophysics.
