Polarization Transport and Polarized Images of a Rotating Braneworld Black Hole

Wen-Hao Deng, Qing-Quan Jiang, Kai Lin +1

We investigate polarized synchrotron emission from an optically thin accretion flow around a rotating braneworld black hole, focusing on how higher-dimensional gravity modifies pho…

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…

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…
