Optical appearance of a thin-shell wormhole with a Hayward profile
Sen Guo, Guan-Ru Li, En-Wei Liang
The optical properties of a thin-shell wormhole (TSW) with a Hayward profile is investigated. Adopting the ray-tracing method, we demonstrate that the TSW's contralateral spacetime…
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…
Observable characteristics of the charged black hole surrounded by thin disk accretion in Rastall gravity
Sen Guo, Guan-Ru Li, En-Wei Liang
The observable characteristics of the charged black hole (BH) surrounded by a thin disk accretion are investigated in the Rastall gravity. We found that the radii of the direct emi…
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…
Shadow thermodynamics of AdS black hole in regular spacetime
Sen Guo, Guan-Ru Li, Guo-Ping Li
The dependence of the black hole (BH) shadow and thermodynamics may be structured in the regular spacetime. Taking the regular Bardeen-AdS BH as an example, the relationship betwee…
