Gravitational Lensing in Cosmological Background/ Seminar Series 7

Speaker: Mojahed ParsiMood

Affiliation: Sharif University of Technology
Title: Gravitational Lensing in Cosmological Background
Date: 4 May 2011
Place: Astronomy seminar, Astronomy school IPM

abstract:

 In this talk, i want to investigate the problem of gravitational lensing in general relativity exactly. Considering a model for a lens in cosmological background, i solve the null geodesic equations in this model and compute deflection angle. Then i compare this results with the usual attitude to this problem and its relation to mass and dark matter.
