Quasinormal Modes of Charged Black Holes in Higher-Dimensional Einstein-Power-Maxwell Theory

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 spacetime dimensionalities. arXiv:2005.08338v2 [gr-qc] 7 Jun 2020

Greybody factor and quasinormal modes of Regular Black Holes

“…Even more, such frequencies depend on i) the geometry and ii) the type of perturbations [25]. Along the years, the study of QNM becomes more essential than ever, and certain seminal works have been performed up to now, for instance see [26][27][28] and more recent works [29][30][31][32][33][34][35][36][37][38][39][40][41][42][43].…”

Quasinormal modes of black holes with a scalar hair in Einstein-Maxwell-dilaton theory

“…For an incomplete list see e.g. [66][67][68][69][70][71][72], and for more recent works [73][74][75][76][77][78][79][80][81][82][83][84][85], and references therein. Within the WKB approximation the QN frequencies are given by…”

Quasinormal modes of massive scalar fields in four-dimensional wormholes: Anomalous decay rate

“…The above discussion indicates that the knowledge of QNMs and quasinormal frequencies (QNFs) are very important to understand the properties of compact objects and distinguish their nature. The QNMs give an infinite discrete spectrum which consists of complex frequencies, ω ¼ ω R þ iω I , where the real part ω R determines the oscillation timescale of the modes, while the complex part ω I determines their exponential decaying timescale (for a review on QNM modes see [7,8] and for recent solutions see [33][34][35][36][37][38][39]).…”
