Scalar field perturbations of the Schwarzschild black hole in the Gödel Universe

arXiv:hep-th/0503029 · doi:10.1103/PhysRevD.71.084015

Abstract

We investigate the scalar field perturbations of the 4+1-dimensional Schwarzschild black hole immersed in a Gödel Universe, described by the Gimon-Hashimoto solution.This may model the influence of the possible rotation of the Universe upon the radiative processes near a black hole. In the regime when the scale parameter of the Gödel background is small, the oscillation frequency is linearly decreasing with , while the damping time is increasing. The quasinormal modes are damping, implying stability of the Schwarzschild-Gödel space-time against scalar field perturbations. The approximate analytical formula for large multipole numbers is found.
