Exact plane gravitational waves in the de Rham-Gabadadze-Tolley model of massive gravity

arXiv:1109.4713 · doi:10.1103/PhysRevD.84.064026

Abstract

We show that the nonlinear massive gravity model of de Rham, Gabadadze, and Tolley admits exact plane gravitational wave solution whose waveform obeys the two-dimensional Helmholtz equation. The solution is valid for arbitrary values of the coefficients of the cubic and quartic terms. In the massless limit the solution reduces to the Aichelburg-Sexl metric in general relativity.
