Quasinormal modes of charged squashed Kaluza-Klein black holes in the Godel universe

We study the quasinormal modes of scalar perturbation in the background of five-dimensional charged Kaluza-Klein black holes with squashed horizons immersed in the Godel universe. Besides the influence due to the compactness of the extra dimension, we disclose the cosmological rotational effect in the wave dynamics. The wave behavior affected by the Godel parameter provides an interesting insight into the Godel universe.
