Dirty Black Holes and Hairy Black Holes [PDF]
Physical Review Letters, 1996 An approach based on considerations of the non-classical energy momentum tensor outside the event horizon of a black hole provides additional physical insight into the nature of discrete quantum hair on black holes and its effect on black hole ...

European Physical Journal C: Particles and Fields, 2019 We study some physical properties of black holes in Null Aether Theory (NAT) – a vector-tensor theory of gravity. We first review the black hole solutions in NAT and then derive the first law of black hole thermodynamics.

Kretschmann Scalar for a Kerr-Newman Black Hole [PDF]
, 1999 I have derived the Kretschmann scalar for a general black hole of mass m, angular momentum per unit mass a, and electric charge Q. The Kretschmann scalar gives the amount of curvature of spacetime, as a function of position near (and within) a black hole.

Holographic complexity of Born–Infeld black holes
European Physical Journal C: Particles and Fields, 2019 In this paper, according to CA duality, we study complexity growth of Born–Infeld (BI) black holes. As a comparison, we study action growth of dyonic black holes in Einstein–Maxwell gravity at the beginning.

Black hole solutions surrounded by perfect fluid in Rastall theory
Physics Letters B, 2017 In this work, we obtain uncharged∖charged Kiselev-like black holes as a new class of black hole solutions surrounded by perfect fluid in the context of Rastall theory.

Scalarization of Taub-NUT black holes in extended scalar-tensor-Gauss-Bonnet theory [PDF]
Journal of High Energy PhysicsRecently, the scalarization of the Schwarzschild black hole has been extensively studied. In this work, we explore the scalarization of the Taub-NUT black hole within the context of the extended scalar-tensor-Gauss-Bonnet theory, which admits a Ricci ...

Black hole masking and black hole thermodynamics [PDF]
Grav.Cosmol.17:276-279,2011, 2011 Masking of black holes means that, for given total mass and Hawking temperatures, these data may correspond to either "pure" black hole or a black hole of a lesser mass surrounded by a massive shell. It is shown that there is one-to one correspondence between this phenomenon and thermodynamics of a black hole in a finite size cavity: masking of black ...

Thermodynamic Black Holes. [PDF]
Entropy (Basel), 2018 Black holes pose great difficulties for theory since gravity and quantum theory must be combined in some as yet unknown way. An additional difficulty is that detailed black hole observational data to guide theorists is lacking. In this paper, I sidestep the difficulties of combining gravity and quantum theory by employing black hole thermodynamics ...

Multioscillating black holes [PDF]
Journal of High Energy Physics, 2021 Abstract We study rotating global AdS solutions in five-dimensional Einstein gravity coupled to a multiplet complex scalar within a cohomogeneity-1 ansatz. The onset of the gravitational and scalar field superradiant instabilities of the Myers-Perry-AdS black hole mark bifurcation points to black resonators and hairy Myers-Perry ...
