Quasinormal-mode analysis of a massive scalar field in a Schwarzschild background via the spectral method
Davide Batic, Anna Chrysostomou, Alan S. Cornell +1
We study the massive scalar quasinormal-mode spectral problem on a Schwarzschild background using an extended Chebyshev spectral method. The massive dispersion relation has a two-s…
Quasinormal modes of Hayward black holes from Schwarzschild to extremality: a comparative spectral analysis
Davide Batic, Denys Dutykh
We study scalar and electromagnetic quasinormal modes of the Hayward black hole and the axial spectrum of a specified Regge--Wheeler-type effective model, from the Schwarzschild li…
An exact Kerr-like rotating Morris--Thorne wormhole: throat, ergoregion and equatorial shadow slice
Mark Sukaiti, Davide Batic, Denys Dutykh
We construct an exact Kerr-like rotating extension of the zero-redshift Morris--Thorne wormhole in a Teo-type stationary, axisymmetric ansatz. The Einstein equations for an anisotr…
Schwarzschild spectral ladders on the negative imaginary axis: Endpoint nonselection, branch-cut phase, and Jost classification
Davide Batic, Denys Dutykh, Mark Essa Sukaiti
Compactified spectral discretisations may yield stable negative-imaginary-axis (NIA) eigenvalue ladders, but finite-matrix convergence does not establish quasinormal poles. For axi…
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…

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…

Davide Batic, Denys Dutykh
We present a comprehensive analysis of quasinormal modes (QNMs) for noncommutative geometry-inspired Schwarzschild black holes, encompassing both non-extreme and extreme cases. By…
