Gravitational Wave Probes of Parity Violation

Leah Jenks
Chicago

Abstract:

In this talk I will discuss gravitational parity violation and its effects on gravitational and cosmological observables. I will first introduce a theory-agnostic parameterization to characterize both amplitude and velocity birefringence in gravitational-wave (GW) propagation as a result of parity violation. Then, I will discuss how these effects can be probed with GW observables, including the stochastic gravitational-wave background and multi-messenger GW/EM events. Lastly, I will discuss how chiral gravitational waves can lead to observable signatures in large scale structure.
