Deviations from Kerr: Polar critical curves and photon rings in a class of separable spacetimes
Hao-Peng Yan, Xiang-Qian Li, Xiao-Jun Yue
Black-hole critical curves and photon rings provide complementary probes of strong-field geometry, motivating a unified analytic description of these observables beyond Kerr and a…
Near-extremal asymptotics and strong cosmic censorship for black holes immersed in a Chaplygin-like dark fluid
Hao-Peng Yan, Zeng-Yi Zhang, Xiang-Qian Li +1
We investigate strong cosmic censorship (SCC) for massless scalar perturbations of electrically neutral black holes immersed in a Chaplygin-like dark fluid (CDF). The matter distri…
Optical Appearance of the Kerr-Bertotti-Robinson Black Hole with a Magnetically Driven Synchrotron Emissivity Model
Zeng-Yi Zhang, Xiang-Qian Li, Hao-Peng Yan +1
We investigate the optical appearance of a Kerr-Bertotti-Robinson (Kerr-BR) black hole illuminated by a geometrically and optically thin accretion disk. Instead of using a phenomen…
