Conference in French: Weak lensing and some of its applications in cosmology
Date: December 7, 2015
Time: 17:00
Summary:
The understanding of light propagation is central in cosmology. It enters the determination of distances but also the causal structure of our universe. This seminar summarizes the properties of weak lensing and some of its new applications that allow us to formulate new tests of general relativity as well as the isotropy of the cosmic expansion. To finish, it will detail a new formalism to deal with the effects of the small scale structures and of their importance in the analysis of the Hubble diagram.
