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…

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…
