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…
Polarized Radiative Transfer of Kerr-Newman Black Hole
Xin Li, Sen Guo, Pei Wang +6
In this analysis, we investigate the polarization radiation imaging of Kerr-Newman black holes, with a particular focus on the impact of black hole charge on photon propagation and…
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…
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…
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…
