Perturbative deflection angle, gravitational lensing in the strong field limit and the black hole shadow
Junji Jia, Ke Huang
A perturbative method to compute the deflection angle of both timelike and null rays in arbitrary static and spherically symmetric spacetimes in the strong field limit is proposed.…

Perturbative deflection angle for signal with finite distance and general velocities
Ke Huang, Junji Jia
We propose a perturbative method to compute the deflection angle of both null and massive particles for source and detector at finite distance. This method applies universally to t…

Perturbative deflection angles of timelike rays
Yujie Duan, Weiyu Hu, Ke Huang +1
Geodesics of both lightrays and timelike particles with nonzero mass are deflected in a gravitational field. In this work we apply the perturbative method developed in Ref. \cite{J…
