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…
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…
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…
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…
Geodesics and Shadows in the Kerr-Bertotti-Robinson Black Hole Spacetime
Xinyu Wang, Yehui Hou, Xi Wan +2
In this work, we investigate geodesics and black hole shadows in the Kerr-Bertotti-Robinson spacetime. We show that the equations of motion for null geodesics are separable and adm…
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…
