Propagation effects of Lorentz violation in gravitational waves
Modified dispersion from isotropic Lorentz-violating operators in the gravitational SME produces birefringence and polarization mixing in gravitational waves, with explicit waveforms for binary black holes and new bounds on the coefficients from GW170817 and GWTC-3 data.
