The spherically symmetric deformation of the Schwarzschild solution owing to the quantum corrections to gravity is known as Kazakov-Solodukhin black-hole metric. Neglecting non-spherical deformations of the background the problem was solved non-perturbatively. Here we analyze the basic characteristics of this geometry, such as: quasinormal modes and grey-body factors of fields of various spin and shadow cast by this black hole. The WKB approach and time-domain integration method, which we used for calculation of quasinormal modes, are in a good concordance. The analytical formula for quasinormal modes is deduced in the eikonal regime. The radius of shadow is decreasing when the quantum deformation is turned on.

  1. Quasinormal spectra of higher dimensional regular black holes in theories with infinite curvature corrections

    gr-qc 2025-09 conditional novelty 5.0 of 10

    For six families of higher-dimensional regular black holes, positive higher-curvature coupling reduces quasinormal-mode oscillation frequencies and damping rates, a trend verified at low and eikonal multipoles.

  2. Gravitational quasinormal modes of the Hayward spacetime

    gr-qc 2025-08 conditional novelty 5.0 of 10

    Gravitational quasinormal modes of the Hayward black hole are computed with WKB and time-domain methods, showing that the quantum parameter gamma raises frequencies, weakens damping, and acts slightly more on the firs...

  3. On new regular charged black hole solutions: Limiting Curvature Condition, Quasinormal modes and Shadows

    gr-qc 2024-11 conditional novelty 5.0 of 10

    The authors introduce two new regular black hole metrics from nonlinear electrodynamics and two Limiting Curvature Condition versions, with numerical results for stability, shadows, and quasinormal modes.

  4. Observational Constraints on Kazakov-Solodukhin Quantum-Deformed Black Holes from M87$^*$ and Sgr A$^*$ Shadows

    gr-qc 2026-07 conditional novelty 4.0 of 10

    EHT shadow sizes of M87* and Sgr A* constrain the Kazakov-Solodukhin deformation parameter η to O(1) ranges while the metric remains asymptotically Schwarzschild.

  5. Bonanno-Reuter regular black hole: quasi-resonances, grey-body factors and absorption cross-sections of a massive scalar field

    gr-qc 2025-10 conditional novelty 4.0 of 10

    Damping of massive scalar quasinormal modes decreases with field mass in the Bonanno-Reuter black hole, and grey-body factors shift to higher frequencies.
