Dark Energy Survey

(survey aimed at mapping the universe's expansion)

The Dark Energy Survey (DES) is a survey of various phenomena that reveal the course of the universe's expansion, including Type Ia Supernovas, Baryon Acoustic Oscillations (BAO), counts of early Galaxy Clusters (CL), and Weak Lensing. Thus it will measure and confirm the existence of Dark Energy. The survey is being conducted with the Cerro Tololo Inter-American Observatory (CTIO) in Chile by an international collaboration of research institutions.

The size of the survey area is 5000 square degrees, about 1/8 of the sky. The camera (DECam, for Dark Energy Camera) will image Visible Light and some Near Infrared (NIR). The telescope is the 4m Victor M. Blanco Telescope.
