Gravitational Lensing in LTB Metric

Mojahed Parsi (Sharif Univ.)

Abstract:

I discuss gravitational lensing with cosmological background and compare it with conventional Schwarzschild method. This work based on numerical solution of geodesic equation in LTB metric, which models a galaxy or a cluster of galaxy with NFW density profile as a lens in a flat universe. It may be useful to compare different definitions of mass in cosmological background.
