General mass formulas for charged Kerr-AdS black holes

Autor: Gao, Yunjiao, Di, Zhenbo, Gao, Sijie

Publikováno v: Phys. Scripta 99 (2024) 9, 095022

It is well-known that the mass of a non-asymptotically flat spacetime cannot be uniquely defined. Some mass formulas for the Kerr-AdS black hole have been found and used in studying black hole thermodynamics. However, the derivations usually need a b

Report

Testing the weak cosmic censorship conjecture for extremal magnetized Kerr-Newman black holes

Autor: Gao, Yunjiao, Gao, Sijie

We test the weak cosmic censorship conjecture for magnetized Kerr-Newman spacetime via the method of injecting a test particle. Hence, we need to know how the black hole's parameters change when a test particle enters the horizon. This was an unresol

Weak cosmic censorship conjecture in higher-dimensional black holes with nonlinear electrodynamic sources

Autor: Li, Zhen, Gao, Yunjiao, Guo, Xiao-Kan

Publikováno v: Phys. Lett. B, 817, 136303 (2021)

The new version of the gedanken experiments proposed by Sorce and Wald are designed to test the validity of the weak cosmic censorship conjecture (WCCC) by overspinning or overcharging the Kerr-Newman black hole in Einstein-Maxwell gravity. Following

Report

Investigating the gedanken experiment to destroy the event horizon of a regular black hole

Autor: Jiang, Jie, Gao, Yunjiao

Publikováno v: Phys. Rev. D 101, 084005 (2020)

Recently, Li and Bambi proposed a hypothesis that the event horizon of a regular black hole can be destroyed because these objects have no gravitational singularity and therefore they are not protected by the weak cosmic censorship conjecture (WCCC).
