SUMMARY:

We investigate the quasinormal modes of several families of higher-dimensional regular black holes arising in gravitational theories that incorporate an infinite tower of higher-curvature corrections to Einstein gravity. Our analysis focuses on how the ringdown phase of gravitational waves for such regular black holes deviates from the predictions of General Relativity. We employ the Wentzel–Kramers–Brillouin (WKB) method to calculate the quasinormal modes and to derive compact analytic expressions in the eikonal approximation. Our results contribute to understanding how possible quantum-gravity-motivated corrections and regularity conditions can manifest in gravitational-wave signals. We study grey-body factors and Hawking radiation of higher-dimensional regular black holes arising in quasi-topological gravity. These spacetimes incorporate infinite–curvature corrections that remove the central singularity while preserving an event horizon and a well-defined semiclassical description. We show that, for all considered regular black hole models, the transmission of radiation and the corresponding Hawking evaporation are systematically suppressed compared to the singular black hole solutions of General Relativity.
