Gravitational lensing; from $\mu$-lensing to cosmic shear experiments
Bernardeau F. (CEA, DSM, SPhT (Service de Physique Théorique), F-91191 Gif-sur-Yvette, FRANCE)Abstract:Année de publication : 2003
These notes present the physics of gravitational lensing in various cosmological contexts. The equations and approximations that are commonly used to describe the displacement field or the amplification effects are presented. Several observational applications are discussed. They range from micro-lensing effects to cosmic shear detection that is a weak lensing effect induced by the large-scale structure of the Universe. The scientific perspectives of this latter application are presented in some details.
