Abstract

Using gravitational decoupling under the requirements of a well-defined event horizon and the source matter satisfying the weak energy condition, we construct nonsingular hairy black holes with spherical or axial symmetry. These solutions emerge from a deformation of the Minkowski vacuum, bridging the novel hairy geometries and the classical Schwarzschild and Kerr solutions at the maximum deformation in their respective sectors.
