Dark Energy Survey
The Dark Energy Survey is a visible and near-infrared survey that aims to probe the dynamics of the expansion of the Universe and the growth of large-scale structure. The collaboration is composed of research institutions and universities from the United States, Australia, Brazil, the United Kingdom, Germany, Spain, and Switzerland. The survey uses the 4-meter Victor M. Blanco Telescope located at NOIRLab's Cerro Tololo Inter-American Observatory in Chile, outfitted with the Dark Energy Camera. This camera allows for more sensitive images in the red part of the visible spectrum and in the near infrared, in comparison to previous instruments. DECam has one of the widest fields of view available for ground-based optical and infrared imaging. The survey has imaged 5,000 square degrees of the southern sky in a footprint that overlaps with the South Pole Telescope and Stripe 82.
