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…

Critical Behavior of Photon Rings in Kerr-Bertotti-Robinson Spacetime
Xi Wan, Zhenyu Zhang, Fang-Stars Wei +2
In this work, we investigate the critical behavior of photon rings in the Kerr-Bertotti-Robinson spacetime, describing a rotating black hole immersed in a background magnetic field…
