Une proposition de satellite dédié pour la mesure de l'Energie Noire

Abstract : Dark energy is one of the most intringing question for cosmology and fundamental physics. I will explain the current experimental results and will focus on future promising probes, mainly supernovae and weak gravitationnal lensing to measure dark energy properties. I will present how the SNAP-L project ( Supernova/Acceleration Probe) is optimised to control uncertainties, combining weak gravitational lensing measurement and Type Ia supernova distance method, over a redshift range up to z = 1.7. As a wide, deep, and colorful Survey, covering 9000 times the area of the Hubble Deep Field to twice as deep in 9 wavelengths bands from the optical to near infrared, SNAP has also a large astronomy capabilities
