D-dimensional Bardeen–AdS black holes in Einstein–Gauss–Bonnet theory

A Kumar, DV Singh, SG Ghosh - The European Physical Journal C, 2019 - Springer
We present a D-dimensional Bardeen like Anti-de Sitter (AdS) black hole solution in Einstein–
Gauss–Bonnet (EGB) gravity, viz., Bardeen–EGB–AdS black holes. The Bardeen–EGB–AdS …

Thermodynamics of a class of regular black holes with a generalized uncertainty principle

RV Maluf, JCS Neves - Physical Review D, 2018 - APS
In this article, we present a study on thermodynamics of a class of regular black holes. Such
a class includes Bardeen and Hayward regular black holes. We obtained thermodynamic …

Corrected form of the first law of thermodynamics for regular black holes

MS Ma, R Zhao - Classical and Quantum Gravity, 2014 - iopscience.iop.org
We show by explicit computations that there is a superficial inconsistency between the
conventional first law of black hole thermodynamics and Bekenstein–Hawking area law for …

Noncommutative Schwarzschild black hole surrounded by quintessence: Thermodynamics, Shadows and Quasinormal modes

B Hamil, BC Lütfüoğlu - Physics of the Dark Universe, 2024 - Elsevier
Abstract In Campos et al.(2022), Campos et al studied the quasinormal modes and shadows
of noncommutative Schwarzschild black holes. Since we know that the quintessence matter …
