2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/227840We study the quasinormal modes of scalar perturbation in the background of five-dimensional charged Kaluza-Klein black holes with squashed horizons immersed in the Gödel 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 Gödel parameter provides an interesting insight into the Gödel universe.11 pages, 4 figures, revised version, accepted for publication in PRDGeneral Relativity and Quantum CosmologyHigh Energy Physics - Theorytext
