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…
Energy conditions in consistent perfect fluid cosmology
Davide Batic, Christian G. Boehmer, Denys Dutykh
Motivated by recent work on consistent fluid couplings in gravity, we study cosmology in the nontrivial model using the Brown variational principle…
Exact solutions for slowly rotating wormholes in the presence of an anisotropic fluid
Davide Batic, Denys Dutykh, Mark Essa Sukaiti
We construct slowly rotating traversable wormholes in the presence of an anisotropic fluid. Starting from a Teo-type stationary, axisymmetric extension of the Morris-Thorne metric,…
