Probing the Penrose Process: Images of Split Hotspots and Their Observational Signatures
Zhixing Zhao, Zhong-Ying Fan, Xiaobao Wang +2
While theoretically established for decades, the Penrose process - energy extraction from rotating black holes - still lacks clear observational evidence. A promising theoretical f…
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…
Semi-analytical Study on the Polarized Images of Black Hole due to Frame Dragging
Xinyu Wang, Songbai Chen, Minyong Guo +1
An initially retrograde accretion flow is transformed into a prograde configuration before plunging into the black hole, as a result of the frame-dragging effect induced by the bla…
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…
