The following is taken from the abstract of the attached observing proposal, which was granted 525 nights of observing time over 5 years on the instrument and telescope detailed within: "The Nobel Prize in Physics for 2011 was awarded for the discovery of the accelerating expansion of the Universe. The primary scientic objective of the Dark Energy Survey (DES) is to address the question: why is the expansion of the Universe speeding up? Is cosmic acceleration due to dark energy or does it require a modication of General Relativity? If dark energy, is it the energy density of the vacuum (Einstein's cosmological constant) or something else? DES will address these questions by measuring the properties of dark energy with unprecedented precision, using four complementary techniques: galaxy clusters, large-scale galaxy clustering (including baryon acoustic oscillations), weak gravitational lensing, and type Ia supernovae. To achieve the requisite precision, we will conduct two optimally interleaved surveys over 525 nights: a wide-area grizY survey covering 5000 sq. deg. to 24th mag and a deeper time-domain griz survey with 5-day cadence covering 30 sq. deg. In response to an NOAO AO in 2003, the DES collaboration was formed and has built the Dark Energy Camera (DECam), a 570- megapixel, red-sensitive imager with 2.2 degree field of view, five uniform, high-throughput filters, a five-element optical corrector, and a hexapod system for active focus and alignment. We have constructed and will operate a data management system to process and serve DES survey data and a Community Pipeline for NOAO to process community data. The DES data products will provide a rich legacy for the astronomy community, and DECam will be an extraordinary asset as a facility instrument on the Blanco Telescope."

以下内容取自所附的观察提案的抽象，该提案被授予525晚观察时间在仪器和望远镜上详细介绍的5年以上的时间：能量还是需要一般的相对性？ IA超新星要达到必要的精度，我们将在525夜进行两次最佳交织的调查：一个覆盖5000平方英尺的广阔的调查。到第24 mag和更深的时间域Griz调查，5天的节奏涵盖30平方英尺。为了响应2003年的NOAO AO，DES协作成立了，并制造了Dark Energial Camera（DECAM），这是一个570兆像素，红色敏感的成像仪，具有2.2度视野，五个均匀的高通量过滤器，五个元素的光学校正器，一个五元素的光学校正器，以及一个可积极的焦点和核心焦点和对准系统。我们已经构建并将操作一个数据管理系统，以处理和提供DES调查数据以及NOAO处理社区数据的社区管道。 DES数据产品将为天文学界提供丰富的遗产，而DECAM将是Blanco望远镜上的设施工具的非凡资产。”
