We present a quantum description of electrically charged spherically symmetric black holes given by coherent states of gravitons in which both the central singularity and the Cauchy horizon are not realised.

  1. Coherent quantum geometry: de Sitter spacetime in different foliations

    gr-qc 2026-08 conditional novelty 6.0 of 10

    In a coherent-state quantum geometry model, the de Sitter metric is reproduced in the Poincaré patch only for finite cosmological time, while the static patch acquires a real singularity at the horizon.

  2. Coherent quantum hairy black holes from gravitational decoupling: regularity, geodesics, and scalar ringdown

    hep-th 2026-02 conditional novelty 6.0 of 10

    Gaussian-smearing the gravitational-decoupling hairy black hole produces a regular core and modified photon rings, lensing, and a claimed but absent ringdown spectrum.

  3. Quantum dust cores of rotating black holes

    gr-qc 2026-01 unverdicted novelty 6.0 of 10

    Quantizing geodesic motion of dust particles in rotating black hole geometries produces many-body ground states whose core size and effective interior geometry depend on angular momentum.

  4. Regular black holes with Minkowskian cores: causal structure and observational degeneracy

    gr-qc 2026-07 conditional novelty 5.0 of 10

    Regular black holes with Minkowskian cores constructed by gravitational decoupling produce shadows and accretion-disk images nearly indistinguishable from Kerr/Schwarzschild despite radically different interiors.

  5. On static and rotating decoupled black holes without inner horizons

    gr-qc 2024-12 conditional novelty 4.0 of 10

    The authors construct a family of static and rotating black hole metrics with an extra 1/r^n hair that, for negative hair parameter, removes the Cauchy horizon and makes the central singularity spacelike.

  6. Analytic models for gravitational collapse

    gr-qc 2024-11 reject novelty 4.0 of 10

    Two time-dependent mass profiles are proposed as exact models of the last stage of Schwarzschild collapse; one develops the curvature singularity immediately, the other only at infinite time, though the second model's...
