Quasinormal Modes of Gauss--Bonnet Black Holes via the Spectral Method: Scalar, Vector, and Tensor Perturbations
Davide Batic, Denys Dutykh
We present a unified study of scalar, vector, and tensor quasinormal modes (QNMs) of Schwarzschild black holes corrected by a Gauss--Bonnet (GB) term in higher dimensions. Using a…
Quasinormal modes of the Kazakov--Solodukhin quantum-corrected black hole: a spectral analysis
Davide Batic, Denys Dutykh, Mark Sukaiti
We compute quasinormal modes of the Kazakov--Solodukhin quantum-corrected black hole using a high-precision Chebyshev spectral method. After factoring out the quasinormal mode asym…
Scalar quasinormal modes of Schwarzschild--anti-de Sitter black holes: spectral analysis and generalized boundary conditions
Davide Batic, Alan S. Cornell, Denys Dutykh
We study quasinormal modes (QNMs) of a minimally coupled massless scalar field on four-dimensional Schwarzschild--anti-de Sitter black holes using a Chebyshev spectral method. Afte…
Quasinormal modes of Bonanno-Reuter black holes via the Spectral Method
Davide Batic, Denys Dutykh, Fabio Scardigli
In this work, we explore the quasinormal modes (QNMs) of the Bonanno-Reuter black hole, one of the first regular black hole metric suggested by the Asymptotically Safe Gravity (ASG…
Quasinormal modes of noncommutative geometry-inspired dirty black holes
Davide Batic, Denys Dutykh, Zeinabou Ahmed Babou
We investigate the quasinormal modes (QNMs) of noncommutative geometry-inspired dirty black holes, focusing on both non-extremal and extremal configurations. These gravitational ob…
A Unified Spectral Approach for Quasinormal Modes of Lee-Wick Black Holes
Davide Batic, Denys Dutykh, Breno Loureiro Giacchini
In this paper, we undertake a comprehensive examination of quasinormal modes linked to Lee-Wick black holes, delving into scalar, electromagnetic, and gravitational perturbations u…
