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…
