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 supernovae, baryon acoustic oscillations,
counts of early galaxy clusters, 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.
The telescope is the Blanco 4m.
