Quasinormal Spectra of Fields of Various Spin in Asymptotically de Sitter Black Holes within Generalized Proca Theory
Milena Skvortsova
We study massless scalar, electromagnetic, and Dirac perturbations of asymptotically de Sitter black holes in generalized Proca theory. These geometries are especially interesting…
Long-lived quasinormal frequencies for regular black hole supported by the Einasto profile in the presence of the magnetic field
Milena Skvortsova
We investigate quasinormal modes, grey-body factors, and absorption cross-sections of a massive scalar field in regular black-hole spacetimes supported by the Einasto density profi…
Arbitrarily long-lived quasinormal modes of proper-time flow black holes
Milena Skvortsova
We investigate the quasinormal modes (QNMs) of a massive scalar field in the background of a regular black hole arising from the proper-time flow in asymptotically safe gravity. Th…
Long Lived Quasinormal Modes of Regular and Extreme Black Holes
Milena Skvortsova
Recently, black hole models in a nonlinear modification of the Maxwell electrodynamics were suggested, possessing simultaneously properties of an extreme charge and regularity (Bro…
Quantum corrected black holes: testing the correspondence between grey-body factors and quasinormal modes
Milena Skvortsova
Grey-body factors and quasinormal modes are two distinct characteristics of radiation near black holes, each associated with different boundary conditions. Nevertheless, a correspo…
