Degree Angular Scale Interferometer


Degree Angular Scale Interferometer

DASI

DASI, pour Degree Angular Scale Interferometer (soit « interféromètre à l'échelle angulaire d'un degré ») est un détecteur dédié à l'observation des anisotropies du fond diffus cosmologique. Il a été réalisé par des chercheurs de l'université de Chicago et du California Institute of Technology, ainsi que du personnel du Center for Astrophysical Research in Antarctica (CARA). L'instrument était basé sur le continent Antarctique.
