Observational features of the rotating Bardeen black hole surrounded by perfect fluid dark matter
Ke-Jian He, Guo-Ping Li, Chen-Yu Yang +1
By employing ray-tracing techniques, we investigate the shadow images of rotating Bardeen black holes surrounded by perfect fluid dark matter. In this work, two models are consider…
Quasinormal modes of regular black holes with sub-Planckian curvature and Minkowskian core
Chen Tang, Yi Ling, Qing-Quan Jiang +1
We investigate the perturbation of the scalar field as well as the electromagnetic field over a sort of regular black holes which are characterized by the sub-Planckian curvature a…
Shadows and accretion disk images of charged rotating black hole in modified gravity theory
He-Bin Zheng, Meng-Qi Wu, Guo-Ping Li +1
In this paper, we study the shadow and images of the accretion disk of Kerr-Newman (KN) black hole (BH) in modified gravity (MOG) theory by using backward ray-tracing method. And,…
The shadow and observational images of the non-singular rotating black holes in loop quantum gravity
Guo-Ping Li, He-Bin Zheng, Ke-Jian He +1
By considering the celestial light source and the thin disk source, we employ the backward ray-tracing method to carefully study the shadow, inner shadow and observational images o…
