Recently the quantum Oppenheimer-Snyder gravitational collapse model has been proposed in loop quantum gravity, providing quantum-corrected Schwarzschild spacetimes as the exterior of the collapsing dust ball. In this paper, the quantum gravity effects on the black hole shadows in this model are studied, and the stability of the quantum-corrected black holes is also analyzed by calculating the quasinormal modes. It turns out that the quantum correction always shrinks the radius of shadows, and the quantum-corrected black holes are stable against the scalar and vector perturbations.

  1. Echoes and quasinormal modes for static loop quantum black bounces

    gr-qc 2026-07 conditional novelty 4.0 of 10

    Scalar perturbations of the loop quantum black bounce spacetime produce echoes in traversable-wormhole configurations with a double-barrier effective potential, but not in regular-black-hole configurations with a sing...

  2. Image of a quantum-corrected black hole without Cauchy horizons illuminated by a static thin accretion disk

    gr-qc 2025-10 conditional novelty 4.0 of 10

    For the no-Cauchy-horizon quantum-corrected metric, a larger quantum parameter produces larger horizon, photon sphere, ISCO, and shadow, with narrower and tighter-spaced photon and lensed rings.

  3. Quantum Black Holes: Perihelion Advance, Quasi Normal Modes and Classical/ Topological Thermodynamics

    gr-qc 2025-07 conditional novelty 4.0 of 10

    A quantum-corrected Schwarzschild black hole is shown to be stable under scalar and electromagnetic perturbations, with thermodynamic topology identical to Reissner-Nordström.

  4. Thermodynamics and Shadows of Kerr black holes endowed with a global monopole charge

    gr-qc 2025-06 reject novelty 4.0 of 10

    The authors derive shadow and thermodynamic quantities for a Kerr-like metric with a global monopole term in Δ, and claim EHT observations constrain the monopole charge α.

  5. Testing Extended Theories of Gravity via Black Hole Photon Rings

    gr-qc 2025-05 conditional novelty 3.0 of 10

    For Konoplya-Zhidenko deformed Schwarzschild black holes, epsilon controls photon sphere, shadow, and photon ring size while a2 and b2 are observationally degenerate, and EHT data constrain epsilon to about -0.09 to 0...
