    Gravitational lensing
    (2023) Rizk, Mai Samir Adly; De La Cruz, Dombriz Alvaro
    Gravitational lensing derives its simplicity from some basic assumptions that are satisfied by most physical situations.The thin lens approximation and weak field approximations were used to build the whole theory and explain the phenomenology up to today. We review the gravitational lensing formalism in weak and strong limits. We discuss the main results of massive dark objects at galactic center as Schwarzschild black hole lenses. We also demonstrate the gravitational lensing analysis in f(R) gravity theories.
