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…
Gravitational-wave imprints of Kerr--Bertotti--Robinson black holes: frequency blue-shift and waveform dephasing
Xiang-Qian Li, Hao-Peng Yan, Xiao-Jun Yue
We investigate the orbital dynamics and gravitational wave signatures of neutral Extreme Mass Ratio Inspirals (EMRIs) in the spacetime of a Kerr black hole immersed in an asymptoti…
Cosmological Constraints on 4D Einstein-Gauss-Bonnet Gravity and Kaniadakis Holographic Dark Energy: Implications for Black Hole Shadows
Xiang-Qian Li, Hao-Peng Yan, Xiao-Jun Yue
The direct imaging of black holes by the Event Horizon Telescope (EHT) enables strong-field tests of gravity. We study the cosmological evolution and the black-hole shadow radius i…
Geodesic structure, shadow and optical appearance of black hole immersed in Chaplygin-like dark fluid
Xiang-Qian Li, Hao-Peng Yan, Xiao-Jun Yue +2
In this study, we focus on a black hole immersed in a cosmological Chaplygin-like dark fluid (CDF), characterized by the equation of state and an additional parameter …
Critical behavior of AdS black holes surrounded by dark fluid with Chaplygin-like equation of state
Xiang-Qian Li, Hao-Peng Yan, Li-Li Xing +1
Supposing the existence of Dark Fluid with a Chaplygin-like equation of state (CDF) as a cosmic background, we obtain a static spherically-symmetric black hole (BH) soluti…
Black holes in Einstein-Gauss-Bonnet gravity with a background of modified Chaplygin gas
Xiang-Qian Li, Bo Chen, Li-Li Xing
Supposing the existence of modified Chaplygin gas with the equation of state as a cosmic background, we obtain a static spherically-symmetric solution to the Einstein-…
Charged Lovelock black holes in the presence of dark fluid with a nonlinear equation of state
Xiang-Qian Li, Bo Chen, Li-li Xing
We consider a model that charged static spherically-symmetric black hole is surrounded by dark fluid with nonlinear equation of state . We find that the energy density…
Spacetime quantization effects on 5-dimensional black string evaporation
Xiang-Qian Li
Spacetime quantization predicts the existence of minimal length and time-interval. Within 5-dimensional Schwarzschild-like black string background, the tunneling of scalar particle…
Massive vector particles tunneling from black holes influenced by the generalized uncertainty principle

This study considers the generalized uncertainty principle, which incorporates the central idea of large extra dimensions, to investigate the processes involved when massive spin-1…
Massive vector particles tunneling from Kerr and Kerr-Newman black holes
Xiang-Qian Li, Ge-Rui Chen
In this paper, we investigate the Hawking radiation of massive spin-1 particles from 4-dimensional Kerr and Kerr-Newman black holes. By applying the Hamilton-Jacobi ansatz and the…
