Curvature radius and Kerr black hole shadow

Wei, Shao-Wen, Zou, Yuan-Chuan, Liu, Yu-Xiao et al.

Understand

We consider applications of the curvature radius of a Kerr black hole shadow and propose three new approaches to simultaneously determine the black hole spin and inclination angle of the observer.

The first one uses only two symmetric characteristic points, i.e., the top and the bottom points of the shadow, and is the smallest amount of data employed to extract information about spin and inclination angle amongst all current treatments.
The second approach shows that only measuring the curvature radius at the characteristic points can also yield the black hole spin and the inclination angle.
The observables used in the third approach have large changes to the spin and the inclination angle, which may give us a more accurate way to determine these parameters.
