Titre Cosmology with weak gravitational lensing
Résumé Weak gravitational lensing is the deflection effect by gravitational potentials while light travels from distanced sources to Earth. This deflection is a powerful tool to probe the matter distribution and to constrain the physics of dark energy. Cosmologists expect that lensing studies can help us improve the knowledge about our Universe, in particular its history and composition. I will start my presentation with an introduction on modern cosmology for people who are not familiar with it. Then I will talk about weak lensing observables and their formalism. The presentation will go on with challenges and difficulties that one might en- counter for lensing studies. And finally, I will present some state-of-art techniques and the perspectives on lensing for next ~10 years.
