5D black holes and mirror (topological) stars from nonlinear electrodynamics: Existence and stability
Kirill A. Bronnikov, Sergei V. Bolokhov, Milena V. Skvortsova
We consider static, spherically symmetric solutions of 5D general relativity with magnetic fields governed by nonlinear electrodynamics (NED) with the Lagrangian , ${\ca…
Stability ranges of magnetic black holes and mirror (topological) stars in 5D gravity
Kirill A. Bronnikov, Sergei V. Bolokhov, Milena V. Skvortsova
We discuss static, spherically symmetric solutions to the 5D Einstein-Maxwell equations (belonging to wide classes of multidimensional solutions known at least from the 1990s) and…
Gravitational quasinormal modes of the Hayward spacetime
S. V. Bolokhov, Milena Skvortsova
We study gravitational quasinormal modes of the Hayward spacetime, a regular black-hole geometry that also admits an interpretation as an effective quantum-corrected solution withi…
Gravitational Quasinormal Modes and Grey-Body Factors of Bonanno-Reuter Regular Black Holes
S. V. Bolokhov, Milena Skvortsova
We study gravitational perturbations of the Bonanno--Reuter quantum-corrected black hole arising in the asymptotic safety scenario, focusing on QNMs and grey-body factors. Assuming…
Correspondence between quasinormal modes and grey-body factors of spherically symmetric traversable wormholes
S. V. Bolokhov, Milena Skvortsova
A correspondence between two distinct spectral problems, quasinormal modes and grey-body factors, has recently been established for a wide class of black holes. Here, we demonstrat…
Review of analytic results on quasinormal modes of black holes
S. V. Bolokhov, Milena Skvortsova
We present a concise review of known analytic results for quasinormal modes of black holes and related spacetimes. Our emphasis is on those regimes where the perturbation equations…
