Title: Quasinormal ringing of black holes in Einstein aether theory
Abstract: The gravitational consequence of local Lorentz violation should show itself in derivation of the characteristic quasinormal ringing of black hole mergers from their general relativity case. In this paper, we study on quasinormal modes (QNMs) of the scalar and electromagnetic field perturbations to Einstein aether black holes. We find that quasinormal ringing of the first kind aether black hole is similar to that of another Lorentz violation model---the standard model extension. Compared to Schwarzschild black hole, both the first and the second kind aether black holes have larger damping rate and smaller real oscillation frequency of QNMs. And the differences are from 0.7 percent to 35 percents, those could be detected by new generation of gravitational antennas.
