We study the absorption of massless scalar waves in a geometry that interpolates between the Schwarzschild solution and a wormhole that belongs to the Morris-Thorne class of solutions. In the middle of the interpolation branch, this geometry describes a regular black hole. We use the partial wave approach to compute the scalar absorption cross section in this geometry. Our results show that black holes and wormholes present distinctive absorption spectra. We conclude, for instance, that the wormhole results are characterized by the existence of quasibound states which generate Breit-Wigner-like resonances in the absorption spectrum.

  1. Absorption spectrum and greybody factors of charged black holes in loop quantum gravity

    gr-qc 2026-08 conditional novelty 6.0 of 10

    The absorption cross section of massless scalar waves by a charged loop-quantum-gravity black hole increases with the quantum parameter in an intermediate frequency band, decreases with charge, and matches classical a...

  2. Transition from Regular Black Holes to Wormholes in Covariant Effective Quantum Gravity: Scattering, Quasinormal Modes, and Hawking Radiation

    gr-qc 2025-02 conditional novelty 6.0 of 10

    For a quantum-corrected spacetime, the fundamental quasinormal mode differs little from Schwarzschild, higher overtones deviate significantly, and wormhole states have extremely long-lived modes.

  3. Accretion of multipolar massive complex scalar field packets by a Schwarzschild black hole

    gr-qc 2026-07 conditional novelty 5.0 of 10

    Mode-by-mode numerical accretion maps show that Gaussian massive scalar packets around a Schwarzschild black hole accrete with efficiency set by k0 and ℓ, acquiring a low-k0 partial-accretion floor when Rs/λC > 1.
