Definition: Dark UNiverse Explorer
Goals: Probing dark energy and dark matter through cosmic shear and supernovae
Description minimale: wide field space mission. The baseline concept consists of a 1.2m telescope with a 0.5 square degree optical CCD camera. It is design to be fast with reduced risks and costs, and to take advan,tage of the synergy between ground based and space observations
PI: Alexandre Réfrégier (CEA)
Status: CNES pre-study completed, proposed for ESA's Cosmic Vision program.
IAS implication: IAS involvement on the technical aspects is under discussion. It can be related to the mechanical and thermal, or optical design as well as the calibration of the instrument. IAS is involved in the definition of the scientific objectives of the mission.
IAS members involved: N. Aghanim, M. Douspis, G. Lagache, M. Langer, J-L. Puget
