From Matter Density to Deflection Angle and Gravitational Lensing Using a Perturbative Method

Peiran Liu, Xiaotian Zhang, Junji Jia

In this work, we develop a perturbative method to compute the deflection angle of null or timelike signals in spacetimes filled with a static and spherically symmetric (SSS) perfec…
