Contribution

It provides the first detailed computation of quasinormal modes for these higher-dimensional charged black holes, including the eikonal limit across multiple dimensions.

Findings

Charge affects the quasinormal frequency spectrum.

Angular degree and overtone number influence the damping and oscillation frequencies.

The eikonal limit spectra vary with space-time dimensionality.

Abstract

We compute the quasinormal frequencies for scalar perturbations of charged black holes in five-dimensional Einstein-power-Maxwell theory. The impact on the spectrum of the electric charge of the black holes, of the angular degree, of the overtone number, and of the mass of the test scalar field is investigated in detail. The quasinormal spectra in the eikonal limit are computed as well for several different space-time dimensionalities.
