New Schwarzschild Black Hole Solution for Kerr-Newman-Like Black Holes

open access: yesSSRN Electronic Journal, 2022
When $\Lambda$ is the cosmological constant about $\left(g^{\theta\theta}\right)^{2}$\cite{3}. We assume that both the macroscopic system and the microscopic system are closed systems, the entropy of the system increases to 0, the entropy of the macroscopic open system increases, and the entropy of the microscopic system decreases.

Generating dynamical black hole solutions [PDF]

open access: yesPhysical Review D, 2004
We prove a theorem that characterizes a large family of non-static solutions to Einstein equations, representing, in general, spherically symmetric Type II fluid. It is shown that the best known dynamical black hole solutions to Einstein equations are particular cases from this family.

Five-dimensional Yang–Mills black holes in massive gravity’s rainbow

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
In this paper, we will analyze a five-dimensional Yang–Mills black hole solution in massive gravity’s rainbow. We will also investigate the flow of such a solution with scale.

Surrounded Vaidya solution by cosmological fields

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
In the present work, we study the general surrounded Vaidya solution by the various cosmological fields and its nature describing the possibility of the formation of naked singularities or black holes.

New regular black hole solutions [PDF]

open access: yesAIP Conference Proceedings, 2011
In the present work we consider general relativity coupled to Maxwell’s electromagnetism and charged matter. Under the assumption of spherical symmetry, there is a particular class of solutions that correspond to regular charged black holes whose interior region is de Sitter, the exterior region is Reissner‐Nordstrom and there is a charged thin‐layer ...

Charged vector particle tunneling from a pair of accelerating and rotating and 5D gauged super-gravity black holes

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
The aim of this paper is to study the quantum tunneling process for charged vector particles through the horizons of more generalized black holes by using the Proca equation. For this purpose, we consider a pair of charged accelerating and rotating black

Dilatonic dyon black hole solutions [PDF]

open access: yesClassical and Quantum Gravity, 2015
Dilatonic black hole dyon solutions with arbitrary dilatonic coupling constant $ \neq 0$ and canonical sign $\varepsilon = +1$ for scalar field kynetic term are considered. These solutions are defined up to solutions of two master equations for moduli funtions. For $ ^2 \neq 1/2$ the solutions are extended to $\varepsilon = \pm 1$, where $\varepsilon

Rotating spacetimes generalizing Lifshitz black holes

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We present a spinning black hole solution in d dimensions with a maximal number of rotation parameters in the context of the Einstein–Maxwell-Dilaton theory.

Black hole as a wormhole factory

open access: yesPhysics Letters B, 2015
There have been lots of debates about the final fate of an evaporating black hole and the singularity hidden by an event horizon in quantum gravity. However, on general grounds, one may argue that a black hole stops radiation at the Planck mass (ħc/G)1/2∼
