Dark Universe

BOSS, eBOSS, DESI

Most of the content of the Universe, about 70%, is dominated by an energetic component that is neither matter nor radiation: dark energy. This mysterious component, first observed in 1998 with supernovae, revolutionized our vision of the evolution of the Universe and is one of the major discoveries of the end of the 20th century.

Edelweiss

Objectives The goal of Edelweiss is to detect the dark matter of our Galaxy through its interactions in detectors operated in underground laboratory.

HESS

Exploring the High Energy gamma ray sky

H.E.S.S. Exploring the High Energy gamma ray sky H.E.S.S stands for "High Energy Stereoscopic System". This telescope system been designed and built by a large international collaboration which includes the DAPNIA as a member.

MEGACAM

Megacam MegaCam A major instrument at the CFHT observatory (Canada-France-Hawaii Telescope) The MegaCam camera was developed for the prime focus of the 3.

SNLS : SuperNova Legacy Survey

SNLS aimed at detecting type Ia supernovae at high redshift for cosmological studies. It belongs to the second generation of experiments in that field, launched after the unexpected discovery of the late acceleration of the Universe expansion rate by the first programs of type Ia supernovae at the end of the1990s.
