Thermodynamics of Kerr-Newman-Bertotti-Robinson black holes
Zelin Zhang, Zhenyu Zhang, Bin Chen
In this work, we extend the thermodynamic analyses of the neutral and specially charged Kerr-Bertotti-Robinson black holes to the general Kerr-Newman-Bertotti-Robinson family, in w…

Shadows and Thin-Disk Images of Kerr-Newman Black Holes in a Bertotti-Robinson Magnetic Field
Xi Wan, Haiyu Wang, Zhenyu Zhang +2
In this paper, we investigate the optical properties of Kerr-Newman-Bertotti-Robinson (KN-BR) black holes. We use the separability of null geodesics to analyze unstable spherical p…
