Magnetic reconnection under centrifugal and gravitational electromotive forces
Zhong-Ying Fan, Fan Zhou, Yuehang Li +2
We examine the physical implications of the centrifugal and gravitational electromotive forces on magnetic reconnection in a Kerr black hole background. We find that both forces in…
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…
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…
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…
Images and flares of geodesic hotspots around a Kerr black hole
Jiewei Huang, Zhenyu Zhang, Minyong Guo +1
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…
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…
