Black hole solutions surrounded by perfect fluid in Rastall theory

open access: yesPhysics 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.

Accretion Into and Emission from Black Holes [PDF]

open access: yes, 1976
Analyses are given of various processes involving matter falling into or coming out of black holes. A significant amount of matter may fall into a black hole in a galactic nucleus or in a binary system.

Entropy of black holes with multiple horizons

open access: yesNuclear Physics B, 2018
We examine the entropy of black holes in de Sitter space and black holes surrounded by quintessence. These black holes have multiple horizons, including at least the black hole event horizon and a horizon outside it (cosmological horizon for de Sitter ...

Uniqueness of near-horizon geometries of rotating extremal AdS(4) black holes [PDF]

open access: yes, 2009
We consider stationary extremal black hole solutions of the Einstein-Maxwell equations with a negative cosmological constant in four dimensions. We determine all non-static axisymmetric near-horizon geometries and all static near-horizon geometries for ...

Holographic complexity of Born–Infeld black holes

open access: yesEuropean 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.

On black hole entropy [PDF]

open access: yesPhysical Review D, 1994
Two techniques for computing black hole entropy in generally covariant gravity theories including arbitrary higher derivative interactions are studied. The techniques are Wald's Noether charge approach introduced recently, and a field redefinition method developed in this paper.

Hairy black holes of Lovelock–Born–Infeld-scalar gravity

open access: yesPhysics Letters B, 2018
In this paper we construct new hairy black holes of Lovelock–Born–Infeld-scalar gravity in diverse dimensions. We study horizon structures of the black holes and find the black holes may possess three horizons, two horizons or one horizon.

Probing the conformal invariance around the nonsingular static spherical black holes with waves

open access: yes上海师范大学学报. 自然科学版, 2023
Conformal invariance can ameliorate or eliminate the singularities residing in the black holes, and it may still exist in the strong gravity regimes close to these black holes.
