Tracing Matter with Weak Lensing Surveys
Abstract
Description
Gravitational weak lensing maps the location of (dark) matter at all scales. The lens-induced distortion field traces gravity fields and can be used to reconstruct the mass distribution in galaxies, groups, clusters of galaxies or large-scale structures. From these reconstructions, one can in principle recover where the matter is, what are its properties and how it is coupled with light and baryons. In the following, we review the present status of weak lensing analysis and discuss the most recent results regarding matter properties in the universe.
