Regular evaporating black holes with stable cores
read the original abstract
A feature shared by many regular black hole spacetimes is the occurrence of a Cauchy horizon. It is then commonly believed that this renders the geometry unstable against perturbations through the mass-inflation effect. In this work, we perform the first dynamical study of this effect taking into account the mass-loss of the black hole due to Hawking radiation. It is shown that the time-dependence of the background leads to two novel types of late-time behavior whose properties are entirely determined by the Hawking flux. The first class of attractor-behavior is operative for regular black holes of the Hayward and renormalization group improved type and characterized by the square of the Weyl curvature growing as $v^6$ at asymptotically late times. This singularity is inaccessible to a radially free-falling observer though. The second class is realized by Reissner-Nordstr{\"o}m black holes and regular black holes of the Bardeen type. In this case the curvature scalars remain finite as $v\rightarrow\infty$. Thus the Hawking flux has a profound effect on the mass-inflation instability, either weakening the effect significantly or even expelling it entirely.

Scalar perturbations and strong cosmic censorship in a regular ABGB-de Sitter black hole spacetime
In regular ABGB-de Sitter black holes, near-extremal scalar perturbations decay fast enough (β>1/2) to violate strong cosmic censorship, and adding scalar mass can push the regularity parameter past β=1.

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

Dark matter production from evaporation of regular primordial black holes
Regular primordial black holes can evaporate completely like singular ones and yield the observed dark matter density under modified cosmological constraints.

Regular black holes with Minkowskian cores: causal structure and observational degeneracy
A new family of regular black holes with Minkowskian cores is built via gravitational decoupling; their shadows and thin-disk images are nearly indistinguishable from Schwarzschild/Kerr, though the weak-energy-conditi...

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