In this study, the gravitational decoupling approach via extended geometric deformation is utilized to generate analytical black hole solutions owing to its simplicity and effectiveness. Considering the external fields surrounding Schwarzschild AdS black holes, we derive hairy black hole solutions in asymptotic AdS spacetime, satisfying the strong and dominant energy conditions. Moreover, we find that if the black hole spacetime is a fluid system, the fluid under each of these conditions is anisotropic.

  1. 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.

  2. 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.

  3. Hair imprints of the gravitational decoupling and hairy black hole spectroscopy

    gr-qc 2025-06 conditional novelty 5.0 of 10

    The quasinormal mode frequencies of three gravitational-decoupling hairy black holes differ from matched Reissner-Nordström black holes by more than the estimated WKB error for the first metric, giving a theoretical h...

  4. Gravitational decoupling and regular hairy black holes: Geodesic stability, quasinormal modes, and thermodynamic properties

    gr-qc 2025-12 conditional novelty 4.0 of 10

    For the regular hairy black hole metric (29), larger β shrinks the ISCO and photon sphere, reduces QNM damping, and adds a canonical-ensemble stable phase.

  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.
