Geodesics and shadows of the spindle-deformed Kerr black hole
Hong-Da Lyu, Mingzhi Wang, Shoulong Li
Recently, a new exact Ricci-flat rotating black-hole solution was constructed in four-dimensional general relativity, in which an additional parameter characterizes a spindle d…
The ring-shaped shadow of rotating naked singularity with a complete photon sphere
Mingzhi Wang, Guanghai Guo, Pengfei Yan +2
We investigate the shadows of Konoplya-Zhidenko naked singularity. In the spacetime of Konoplya-Zhidenko naked singularity, not only can unstable retrograde light ring (LR) exist,…
Determination of the spin parameter and the inclination angle by the relativistic images in black hole image
Mingzhi Wang, Songbai Chen, Jiliang Jing
We studied the relativistic images caused by strong gravitational lensing in Kerr black hole images, which carry some essential signatures about the black hole space-time. We defin…
Chaotic Shadows of Black Holes: A Short Review
Mingzhi Wang, Songbai Chen, Jiliang Jing
We give a brief review on the formation and the calculation of black hole shadow. Firstly, we introduce the conception of black hole shadow and the current works on a variety of bl…
