Optical Images of the Braneworld Black Hole Surrounded by an Optically Thin Accretion Disk
Wen-Hao Deng, Sen Guo, Qing-Quan Jiang +2
This work examines the observational signatures of rotating black holes with tidal charge in the Randall--Sundrum braneworld scenario. Combining an elliptic-integral-based analytic…
Polarization Signatures of Rotating Black Holes in Perfect Fluid Dark Matter Spacetimes
Yu-Xiang Huang, Sen Guo, En-Wei Liang +2
Motivated by horizon-scale polarization observations of M87^{*}, we investigate polarized emission from rotating black holes (BHs) immersed in a perfect fluid dark matter (PFDM) ba…
Impact of Perfect Fluid Dark Matter on the Appearance of Rotating Black Hole
Huang Yu-Xiang, Guo Sen, Liang En-Wei +1
Understanding how dark matter affects the immediate environment of black holes (BHs) is crucial for interpreting horizon-scale observations. We study rotating BHs surrounded by per…
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…
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…
Image of the Kerr-Newman black hole surrounded by a thin accretion disk
Sen Guo, Yu-Xiang Huang, En-Wei Liang +3
The image of a Kerr-Newman (KN) black hole (BH) surrounded by a thin accretion disk is derived. By employing elliptic integrals and ray-tracing methods, we analyze photon trajector…
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…
Influence of Accretion Flow and Magnetic Charge on the Observed Shadows and Rings of the Hayward Black Hole
Sen Guo, Guan-Ru Li, En-Wei Liang
The feature of the observed shadows and rings of an astrophysical black hole (BH) may depend on its accretion flows and magnetic charge. We find that the shadow radii and critical…
