Polarization Architecture of Steady GRMHD Jets from the Horizon to Infinity
Zhenyu Zhang, Yehui Hou, Yu Song +2
We develop a semi-analytic framework for stationary, axisymmetric GRMHD jets that efficiently generates resolved polarized images from the near-horizon region out to $\sim 10^5\,r_…
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…
Distorting Kerr Images with Parity-Odd Scalar Hair
Qian Wan, Yehui Hou, Yang Huang +3
We investigate thin-disk imaging of Kerr black holes with synchronized scalar hair, focusing on backreacted parity-odd excited states of a complex scalar field minimally coupled to…
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…
Critical Behavior of Photon Rings in Kerr-Bertotti-Robinson Spacetime
Xi Wan, Zhenyu Zhang, Fang-Stars Wei +2
In this work, we investigate the critical behavior of photon rings in the Kerr-Bertotti-Robinson spacetime, describing a rotating black hole immersed in a background magnetic field…
