Null Geodesics in the Reissner-Nordström Black Hole Spacetime Pierced by a Cosmic String
Tianxu Huo
In this paper, we investigate null geodesics in the spacetime of a Reissner-Nordström black hole pierced by a cosmic string. Analysis of the equations of motion reveals that null g…

Corrected first law of thermodynamics for dynamical regular black holes
Tianxu Huo, Chengzhou Liu
In this work, we establish the corrected first law of thermodynamics for dynamical regular black holes on both the event horizon and apparent horizon. We find that the temperature…
