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 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…
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,…
Noncommutative geometry-inspired wormholes supported by quasi-de Sitter and Chaplygin-like equations of state
D. Batic, D. Dutykh, M. Essa Sukaiti
We construct static, spherically symmetric wormhole solutions with a nontrivial redshift function, inspired by noncommutative geometry, in which point sources are replaced by Gauss…
Exact Spinning Morris-Thorne Wormhole: Causal Structure, Shadows, and Multipole Moments
Davide Batic, Denys Dutykh, Mark Essa Sukaiti
We construct an exact spinning generalisation of the Morris-Thorne traversable wormhole supported by an anisotropic fluid. Within the Teo wormhole ansatz with unit lapse and Morris…
