Distinct Near-Horizon Trend of Synchrotron Polarization in Kerr Spacetime
Yehui Hou, Jiewei Huang, Bin Chen
We show that the near-horizon expansion of the linear polarization vector for synchrotron emission in a Kerr background admits a distinct analytic form. For emission from a station…
Black Hole Ringdown Seen in Photon Polarization Swings
Jiewei Huang, Yehui Hou, Zhen Zhong +2
Light propagating through a perturbed spacetime could imprint the underlying gravitational waveform directly onto electromagnetic observables. In this Letter, we develop a covarian…
Non-thermal Synchrotron Emission and Polarization Signatures during Black Hole Flux Eruptions
Fan Zhou, Jiewei Huang, Yuehang Li +4
In this work, we investigate synchrotron emission and the observational signatures of anisotropic non-thermal electrons during magnetic-flux eruptions in a magnetically arrested di…
Near-Horizon Polarization as a Diagnostic of Black Hole Spacetime
Yehui Hou, Jiewei Huang, Minyong Guo +2
A key challenge in imaging supermassive black holes is disentangling gravitational effects from plasma physics in order to accurately determine spacetime properties, particularly b…
Coport: A New Public Code for Polarized Radiative Transfer in a Covariant Framework
Jiewei Huang, Liheng Zheng, Minyong Guo +1
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…
