Gravitational Lensing: From μ-Lensing to Cosmic Shear Experiments
2005These 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

Monthly Notices of the Royal Astronomical SocietyABSTRACT In this paper, we investigate the impact of higher-order distortions on the precise measurement of weak gravitational lensing shear and flexion. We begin by defining$x_\mathrm{ s} = \theta /r_\mathrm{ s}$ generalized higher-order distortions and outlining methods for measuring them. Then, using several lens models, we examine

We demonstrate that topological voids in Regge calculus produce quantitative gravita-tional lensing signals with a unique, falsifiable prediction: an annular convergence ring atthe toroidal void major radius (Rmaj ≈ 100 kpc) that no spherically symmetric dark mat-ter model can produce.
