Shadow and Optical Imaging in Einstein-Maxwell-Dilaton Black Hole
Junlin Qin, Hong-Er Gong, Yusen Wang +4
This paper investigates photon motion in black hole of Einstein-Maxwell-dilaton theory, exploring black hole shadows and observational characteristics under various accretion model…
The shadows and photon rings of two minimal deformations of Schwarzschild black holes
Hong-Er Gong, Junlin Qin, Yusen Wang +4
This paper primarily investigates the optical characteristics of two minimal Schwarzschild black hole deformations, the Kazakov-Solodukhin and Ghosh-Kumar black holes, under differ…
Image of a time-dependent rotating regular black hole
Sen Guo, En-Wei Liang, Yu-Xiang Huang +4
In this study, we develop a modeling framework based on spatio-temporal generalized random fields to simulate the time-evolving accretion flows and their associated imaging signatu…
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…
A Novel Jet Model for the Novikov-Thorne Disk and its Observable Impact
Sen Guo, Pei Wang, Ke-Jian He +3
Recent high-resolution observations have established a strong link between black hole jets and accretion disk structures, particularly in the 3.5 mm wavelength band [Nature. 616, 6…
Influences of accretion flow and dilaton charge on the images of Einstein-Maxwell-dilation black hole
Gang Chen, Sen Guo, Jia-Shuo Li +3
The characteristics and images of Einstein-Maxwell-Dilaton (EMD) black holes are examined in this paper, focusing on their effective potential, photon trajectories, and images with…
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 gravitation…
