Unique Imprint of Black Hole Spin on the Polarization of Near-Horizon Images

Autor: Hou, Yehui, Huang, Jiewei, Mizuno, Yosuke, Guo, Minyong, Chen, Bin

Extracting information about the gravitational background from black hole images is both important and challenging. In this study, we use a physically motivated plasma model, typically applied to stationary, axisymmetric spacetimes, to demonstrate th

Coport: A New Public Code for Polarized Radiative Transfer in a Covariant Framework$^\spadesuit$

Autor: Huang, Jiewei, Zheng, Liheng, Guo, Minyong, Chen, Bin

General relativistic radiative transfer calculations are essential for comparing theoretical models of black hole accretion flows and jets with observational data. In this work, we introduce Coport, a novel public code specifically designed for covar

Images and flares of geodesic hotspots around a Kerr black hole

Autor: Huang, Jiewei, Zhang, Zhenyu, Guo, Minyong, Chen, Bin

In this study, we develop a numerical method to generate images on an observer's screen, formed by radiation from hotspots on any timelike orbits outside a black hole. This method uses the calculation of fractional numbers, enabling us not only to pr
