Photon Motion and Shadows of Rotating Black Holes with Nonlinear Electromagnetic and Anisotropic Matter Fields
Mou Xu, Jianbo Lu, Yu Liu +1
This paper investigates the effects of the nonlinear electromagnetic field and the anisotropic matter field on photon motion, shadow structures, and the energy emission rate of a r…
Constraint on magnetized black bounce spacetime from HFQPOs data and the selection of resonance models via information criterion
Shining Yang, Jianbo Lu, Mou Xu +1
This paper primarily explores the dynamics of charged particle in the magnetized SV spacetime, and constrains the parameters of the SV spacetime along with its surrounding magnetic…
Observational constraints on the Kerr and its several single-parameter modified spacetimes using quasi-periodic oscillation data
Shining Yang, Jianbo Lu, Wenmei Li +2
This paper investigates the dynamical effects of particles moving in the Kerr spacetime and its nine single-parameter modified spacetimes, including Bardeen, Ayon-Beato and Garcia…
Particle dynamics and optical appearance of charged spherically symmetric black holes in bumblebee gravity
Mou Xu, Jianbo Lu, Ruonan Li +2
In this paper, we study the particle dynamics, shadow, and optical appearance of charged black holes (BHs) in bumblebee gravity. Firstly, we find that the Lorentz-violation paramet…
Optical Appearance and Shadow of Kalb-Ramond Black Hole: Effects of Plasma and Accretion Models
Mou Xu, Ruonan Li, Jianbo Lu +2
In this paper, we study the effect of the presence of plasma and different accretion models on the shadow and optical appearance of static spherically symmetric black holes contain…
Research on high-frequency quasi-periodic oscillations in black bounce-type spacetime
Jianbo Lu, Shining Yang, Yuying Zhang +2
This paper investigates the high frequency quasi-periodic oscillations (HFQPOs) phenomenon around the black bounce-type (BBT) spacetime using the resonance models. We calculated th…
