We show that these black holes have arbitrarily short hair, and argue for stability by showing that they can arise from dynamical collapse. We also show that a recent `no short hair' theorem does not apply to these solutions.doi:10.1142/S0218271897000340David Brown, J....
We show that in all theories in which black hole hair has been discovered, the region with non-trivial structure of the non-linear matter fields must extend beyond $3/ 2$ the horizon radius, independently of all other parameters present in the theory. We argue that this is a universal ...

A connection between regular black holes and horizonless ultracompact objects was proposed in Carballo-Rubio et al. (JHEP 08:046, 2023,arXiv:2211.05817[gr-qc]). In this paper, we construct a model of a horizonless compact object, specifically an anisotropic gravastar with continuous pressure, t...

Classical black holes refer to massive objects in space that decay into final states characterized by a high multiplicity of high-energy particles, mainly jets from quark and gluon emissions.

galaxy contains asupermassive black holeat its center, with a mass ranging from millions to billions ofsolar masses. Black holes are entirely specified by their mass,angular momentum, andelectric charge(likely∼0): the no-hair theorem. For a compact review onastrophysical black holessee[74,75...
These results have provided the first examples of black holes with conformal scalar hair in d > 4 where no-go results had been reported previously [63]. The hairy black holes have been found to have incredibly rich thermodynamics including isolated critical points and black hole λ-lines [35,...
even the current spins of stellar-mass black holes are challenging to measure. As we discuss, major inroads have been made in black hole spin estimates via analysis of iron lines and continuum emission, with reasonable agreement when both types of estimate are possible for individual objects, and...
