Energy Extraction via Magnetic Reconnection from Rotating ModMax Black Holes
Shi-Hao Wang, Ke-Jian He, Guo-Ping Li +1
Magnetic reconnection has been widely recognized as an important mechanism for extracting energy from rapidly rotating black holes. We find that magnetic reconnection can also effi…
Optical Images of Mini Boson Stars in Palatini Gravity
Xiao-Xiong Zeng, Chen-Yu Yang, Yu-Xiang Huang +3
We investigate the optical properties of mini boson stars within the framework of Palatini gravity, adopting a quadratic form , where is the gravitati…
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…
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…
