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_…
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…
Hybrid Black Hole and Disk-Driven Jets: Steady Axisymmetric Ideal MHD Modeling
Yu Song, Yehui Hou, Lei Huang +1
Improved observational precision in relativistic jets has underscored the need for tractable theoretical models. In this study, we construct a semi-analytical hybrid jet model that…
Autocorrelation signatures in time-resolved black hole flare images: secondary peaks and convergence structure
Zhenyu Zhang, Yehui Hou, Minyong Guo +2
The strong gravitational field of a black hole bends light, forming multi-level images, yet extracting precise spacetime information from them remains challenging. In this study, w…
Polarization Patterns of the Hotspots Plunging into a Kerr Black Hole
Bin Chen, Yehui Hou, Yu Song +1
The multi-wavelength polarized light signals from supermassive black holes have sparked many studies on polarized images of accretion disks and hotspots. However, the polarization…
Imaging thick accretion disks and jets surrounding black holes
Zhenyu Zhang, Yehui Hou, Minyong Guo +1
Based on the horizon-scale magnetofluid model developed in [arXiv:2309.13304], we investigate the millimeter-wave images of a geometrically thick accretion disk or a funnel wall, i…
Imaging a Semi-Analytical Jet model Generated by 3D GRMHD Simulation
Ye Shen, Yehui Hou, Zhong-Ying Fan +2
Employing 3D GRMHD simulation, we study the images of a geometrically thin jet, whose emissions concentrate on its surface, for accretion system surrounding a central spinning BH.…
