Abstract
We investigate the scalar field perturbations of the -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.
