Optical Appearances of Accreting Ellis-Bronnikov Wormholes Observed from Both Sides of Throats
Yu-Hao Cui, Kai Lin, Sen Guo +2
This study investigates the optical appearance of the Ellis-Bronnikov wormhole as viewed from both sides of its throat, under conditions of optically thick and thin accretion. By s…
Image of the time-dependent black hole
Yu Liang, Sen Guo, Kai Lin +3
The Event Horizon Telescope's 2024 observations report a shift in the position angle of the brightness asymmetry in M87*, revealing time variability in the black hole's image. In t…
Optical appearance of numerical black hole solutions in higher derivative gravity
Yu-Hao Cui, Sen Guo, Yu-Xiang Huang +2
The optical appearance of the numerically black hole solutions within the higher derivative gravity illuminated by an accretion disk context is discussed. We obtain solutions for n…
Rastall gravity: accretion disk image in radiation fields context and visual transformations compared to Reissner-Nordstrom black holes
Yu-Xiang Huang, Sen Guo, Yu Liang +3
Our study investigates the astronomical implications of Rastall gravity, particularly its behavior amidst a radiation field compared to Reissner-Nordstrom (RN) black holes. Our res…
Influence of accretion disk on the optical appearance of the Kazakov-Solodukhin black hole
Yu-Xiang Huang, Sen Guo, Yu-Hao Cui +2
The optical characteristics of the Kazakov-Solodukhin (KS) black hole (BH) surrounded by a thin disk is investigated. By utilizing the ray-tracing technique, we derive the the dire…
Unveiling the unconventional optical signatures of regular black holes within accretion disk
Sen Guo, Yu-Xiang Huang, Yu-Hao Cui +4
The optical characteristics of three types of black holes (BHs) surrounded by a thin accretion disk are discussed, namely the Schwarzschild BH, Bardeen BH, and Hayward BH. We calcu…
