The sky observed from the sea deeps
Overview
Most of our current knowledge of the Universe comes from the observation of photons.
Photons have many advantages as cosmic information carriers: they are copiously produced, they are stable and electrically neutral, they are easy to detect over a wide energy range, and their spectrum carries detailed information about the chemical and physical properties of the source.
A new generation observatory to explore the high energy Universe.
Une nouvelle génération d'observatoire pour explorer l'Univers à haute énergie.
Objectives
The goal of Edelweiss is to detect the dark matter of our Galaxy through its interactions in detectors operated in underground laboratory.
The EROS experiment, searching for massive compact objects in our galaxy, showed that at most 7 % of our local missing mass could be accounted for by such objects, that is by ordinary matter.

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. This instrument is dedicated to the observation of high energy gamma ray sources with energies above a few tens of GeV.
