Résumé

Over the past few decades it has become clear that most of the mass in the Universe is in an unseen form we call dark matter. I will present the observational evidence leading to this remarkable realization and then focus in particular on the tool of gravitational lensing and how we can use lensing to study the distribution of matter in the universe. I will finish my talk with a discussion of the discovery of dark energy and discuss possibilities for what this mysterious ’energy’ might be. by Laura Parker https://www.procyon.espci.fr/fr/Conferences/The-dark-Universe.html
