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…

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…

Holographic Einstein rings of a Gauss-Bonnet AdS black hole

Xiao-Xiong Zeng, Ke-Jian He, Jin Pu +1

Based on the AdS/CFT correspondence, we studied the holographic Einstein images of a Gauss-Bonnet AdS black hole in the bulk from a given response function on AdS boundary. For the…

QED and accretion flow models effect on optical appearance of Euler-Heisenberg black holes

Xiao-Xiong Zeng, Ke-Jian He, Guo-Ping Li +2

Taking the quantum electrodynamics (QED) effect into account, we investigate the geometrical-optics appearance of the Euler-Heisenberg (EH) black hole (BH) under the different accr…

The shadow and photon sphere of the charged black hole in Rastall gravity

Sen Guo, Ke-Jian He, Guan-Ru Li +1

Considering a charged black hole (BH) surrounded by a perfect fluid radiation field (PFRF) in Rastall gravity, we investigate this BH shadow and photon sphere on different spherica…
