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…
Invertible Diffusion Models for Compressed Sensing
Bin Chen, Zhenyu Zhang, Weiqi Li +5
While deep neural networks (NN) significantly advance image compressed sensing (CS) by improving reconstruction quality, the necessity of training current CS NNs from scratch const…
QED Effects on Kerr-Newman Black Hole Shadows
Shaobing Yuan, Changkai Luo, Zezhou Hu +2
Incorporating first-order QED effects, we explore the shadows of Kerr-Newman black holes with a magnetic charge through the numerical backward ray-tracing method. Our investigation…
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…
