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…
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…
