We model gravitating relativistic 3D spheres composed of an anisotropic fluid in which the radial and transverse components of the pressure correspond to the vacuum energy and a generalized polytropic equation-of-state, respectively. By using the generalized Tolman-Oppenheimer-Volkoff (TOV) equation, and solving the complete system of equations for these anisotropic generalized polytropic spheres, for a given range of model parameters, we find three novel classes of asymptotically AdS black hole solutions with regular core. We show the regularity of the solutions using curvature scalars and the formalism of geodesic completeness. Then, using the eigenvalues of the Riemann curvature tensor, we consider the effects of repulsive gravity in the three static 3D regular black holes, concluding that their regular behavior can be explained as due to the presence of repulsive gravity near the center of the objects. Finally, we study the stability of the regular black holes under the flow of the energy through the Cauchy horizon.

  1. Evaporating cosmologically coupled black holes

    astro-ph.CO 2026-07 conditional novelty 6.0 of 10

    If a black hole's mass grows with cosmic expansion, Hawking evaporation is slowed or reversed, weakening gamma-ray bounds on primordial black holes.

  2. Topological regular black holes without Cauchy horizon

    gr-qc 2025-05 conditional novelty 6.0 of 10

    Hyperbolic and toroidal black hole metrics are constructed with finite curvature invariants and a single horizon, so no Cauchy horizon, and a generalized areal radius extends this to spherical topology.

  3. Optimal Control Theory of the (2+1)-Dimensional BTZ Black Hole

    gr-qc 2025-12 conditional novelty 5.0 of 10

    Geodesics of the Weinhold and Ruppeiner thermodynamic metrics are computed for the BTZ black hole and interpreted as optimal evaporation/accretion protocols.
