Long-lived massive scalar modes, grey-body factors, and absorption cross sections of the Reissner--Nordström-like brane-world black hole
Zainab Malik
We study quasinormal modes, including the quasi-resonant regime, grey-body factors, and absorption cross sections of a massive scalar field in a Reissner--Nordström-like brane-wor…
Thermodynamic, Optical, and Orbital Signatures of Regular Asymptotically Flat Black Holes in Quasi-Topological Gravity
Zainab Malik
This study provides an analytic and numerical characterization of a class of regular, asymptotically flat black holes described by a deformed static spherical metric. The model is…
Gravitational perturbations of the Hayward spacetime and testing the correspondence between quasinormal modes and grey-body factors
Zainab Malik
The paper studies axial gravitational perturbations of the Hayward black hole, a regular geometry that also arises as an effective solution in asymptotically safe gravity. By compu…
Grey-Body Factors for Scalar and Dirac Fields in the Euler-Heisenberg Electrodynamics
Zainab Malik
We study grey-body factors of neutral scalar and Dirac fields in the background of charged black holes arising in the Einstein--Euler--Heisenberg (EEH) theory. The Euler--Heisenber…
Perturbations and Quasinormal Modes of the Dirac Field in Effective Quantum Gravity
Zainab Malik
Recently, two models of quantum-corrected Schwarzschild-like black holes were developed within Effective Quantum Gravity, and the spectra of bosonic perturbations have been analyze…
Analytical QNMs of fields of various spin in the Hayward spacetime
Zainab Malik
By employing an expansion in terms of the inverse multipole number, we derive analytic expressions for the quasinormal modes (QNMs) of scalar, Dirac, and Maxwell perturbations in t…
