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.

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 ...

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.

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.

Effects of (un)usual asymptotics on shadows and lensing of rotating black holes: Numerical and perturbative treatments

open access: yesPhysics Letters B
We consider the slowly rotating black hole with non-flat, non-(A)dS asymptotics and the rotating black holes with AdS asymptotics in the Einstein-Maxwell-dilaton (EMD) theory, and compare the shadows for such black holes with the Kerr-Newman-AdS black ...

Martin Heidegger and the Being and Time of Black Holes [PDF]

open access: yesФилософия и космология, 2020
Scientific narratives about cosmology often present black holes as frightening objects of both creation and destruction, the centres of which are concealed behind event horizons.

Thermodynamics of the Schwarzschild and the Reissner–Nordström black holes with quintessence

open access: yesNuclear Physics B, 2016
In this paper, we study the thermodynamics of the Schwarzschild and the Reissner–Nordström black holes surrounded by quintessence. By using the thermodynamical laws of the black holes, we derive the thermodynamic properties of these black holes and we ...

Universal thermodynamic topological classes of rotating black holes

open access: yesPhysics Letters B
In a recent study, Wei et al. (2024) [96] proposed a universal classification scheme that interprets black hole solutions, including the four-dimensional Schwarzschild, Reissner-Nordström (RN), Schwarzschild-AdS, and RN-AdS black hole solutions, as ...
