Abstract:

The direct detection of gravitational waves provides the opportunity to measure fundamental aspects of gravity that have never been directly probed before, like the polarization of gravitational waves. We show how long-lived signals (resolvable or stochastic) may be used to measure all 6 possible gravitational polarizations with current detectors. This will allow us to obtain new model-independent, dynamical constraints on deviations from general relativity. We demonstrate this framework on multiple potential sources using simulated data from three advanced-era detectors at design sensitivity.
