Using the black string between two branes as a model of a brane-world black hole, we compute the gravity wave perturbations and identify the features arising from the additional polarizations of the graviton. The standard four-dimensional gravitational wave signal acquires late-time oscillations due to massive modes of the graviton. The Fourier transform of these oscillations shows a series of spikes associated with the masses of the Kaluza-Klein modes, providing in principle a spectroscopic signature of extra dimensions.

  1. Massive Scalar Quasinormal Modes, Greybody Factors, and Absorption Cross Section of a Parity-Symmetric Beyond-Horndeski Black Hole

    gr-qc 2026-05 unverdicted novelty 6.0

    Increasing the mass of a scalar field around a parity-symmetric beyond-Horndeski black hole strongly reduces the damping rate of quasinormal modes while suppressing low-frequency absorption and shifting efficient abso...

  2. Two types of quasinormal modes of Casadio-Fabbri-Mazzacurati brane-world black holes

    gr-qc 2026-02 unverdicted novelty 6.0

    Quasinormal modes of massive scalars in CFM brane-world black holes split into two types, with modes disappearing at critical masses where real or imaginary frequency parts reach zero.

  3. Long-lived massive scalar modes, grey-body factors, and absorption cross sections of the Reissner--Nordstr\"om-like brane-world black hole

    gr-qc 2026-05 unverdicted novelty 5.0

    Positive tidal charge in this brane-world black hole lowers the effective potential barrier, pushes massive scalar quasinormal modes toward arbitrarily long lifetimes, and increases transmission and absorption.

  4. Quasi-resonances in the vicinity of Einstein-Maxwell-dilaton black hole

    gr-qc 2026-04 unverdicted novelty 5.0

    Increasing the mass of a perturbing scalar field around Einstein-Maxwell-dilaton black holes strongly suppresses damping in several quasinormal branches, producing quasi-resonant long-lived oscillations.

  5. Long-lived quasinormal modes, shadows and particle motion in four-dimensional quasi-topological gravity

    gr-qc 2026-03 unverdicted novelty 5.0

    Massive scalar quasinormal modes in quasi-topological black holes become long-lived as scalar mass grows, while photon-sphere radius, shadow size, and ISCO exhibit moderate deviations from Schwarzschild.

  6. Wave and particle probes of a regular T-duality-inspired black hole with gravitational self-energy

    gr-qc 2026-07 conditional novelty 4.0

    Increasing zero-point length makes photon and ISCO orbits more compact in ADM units while heavier scalars raise oscillation frequency and suppress damping on this regular self-energy black hole.

  7. Massive scalar quasinormal modes of an asymptotically flat regular black hole supported by a phantom Dirac--Born--Infeld field

    gr-qc 2026-04 unverdicted novelty 4.0

    Massive scalar quasinormal modes in this DBI-supported regular black hole show higher oscillation frequencies and lower damping as field mass increases, with larger regularity scales producing softer and longer-lived ringing.

  8. Telling tails and quasi-resonances in the vicinity of Dymnikova regular black hole

    gr-qc 2026-01 unverdicted novelty 4.0

    Massive scalar perturbations on the Dymnikova regular black hole exhibit growing oscillation frequencies, reduced damping rates leading to quasi-resonances, power-law oscillatory tails, and mass-dependent suppression ...

  9. Quasinormal modes of black holes: from astrophysics to string theory

    gr-qc 2011-02 accept novelty 1.0

    This review surveys calculations and interpretations of quasinormal modes for black holes in astrophysics, higher dimensions, and holographic duals without presenting new results.
