摘要:

宇宙大会近红外深河外遗留巡天(CANDELS)的目的是记录前三分之一的星系演化,在大约红移(z)范围8- 1.5。它将使用哈勃太空望远镜上的三个独立的相机对> 250,000个遥远的星系进行成像,从中紫外到近红外,并将发现和测量z>1.5的Ia型超新星,以测试它们作为宇宙学可测量蜡烛的准确性。选择了五个主要的多波长天空区域,每个区域都具有广泛的辅助数据。使用五个相距甚远的场可以减少宇宙的方差,并产生统计上可靠的完整星系样本,样本的恒星质量低至10^9 M_ \odot至z \approx 2,达到星系紫外光度函数(UVLF)的拐点至z \approx 8。该测量覆盖了大约800弧分^[2],分为两部分。CANDELS/Deep测量(5σ点源极限H=27.7等)覆盖了GOODS-N和GOODS-S范围内的\sim 125弧分^[2]。CANDELS/Wide巡天包括GOODS和三个附加场(EGS、COSMOS和UDS),覆盖整个区域,达到5σ点源极限H \gtrsim 27.0 mag.与哈勃超深场一起,该战略创建了一个三层“婚礼蛋糕”方法,已被证明对河外巡天是有效的。调查的数据是非专有的,对各种科学调查都很有用。在本文中,我们描述了调查的基本动机,CANDELS团队的科学目标和由此产生的观测要求,字段选择和几何形状,以及观测设计。哈勃望远镜的数据处理和产品在一份配套文件中介绍。

英文摘要:

The Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS) is designed to document the first third of galactic evolution, over the approximate redshift (z) range 8--1.5. It will image >250,000 distant galaxies using three separate cameras on the Hubble Space Telescope, from the mid-ultraviolet to the near-infrared, and will find and measure Type Ia supernovae at z>1.5 to test their accuracy as standardizable candles for cosmology. Five premier multi-wavelength sky regions are selected, each with extensive ancillary data. The use of five widely separated fields mitigates cosmic variance and yields statistically robust and complete samples of galaxies down to a stellar mass of 10^9 M_\odot to z \approx 2, reaching the knee of the ultraviolet luminosity function (UVLF) of galaxies to z \approx 8. The survey covers approximately 800 arcmin^2 and is divided into two parts. The CANDELS/Deep survey (5σ point-source limit H=27.7 mag) covers \sim 125 arcmin^2 within GOODS-N and GOODS-S. The CANDELS/Wide survey includes GOODS and three additional fields (EGS, COSMOS, and UDS) and covers the full area to a 5σ point-source limit of H \gtrsim 27.0 mag. Together with the Hubble Ultra Deep Fields, the strategy creates a three-tiered "wedding cake" approach that has proven efficient for extragalactic surveys. Data from the survey are nonproprietary and are useful for a wide variety of science investigations. In this paper, we describe the basic motivations for the survey, the CANDELS team science goals and the resulting observational requirements, the field selection and geometry, and the observing design. The Hubble data processing and products are described in a companion paper.
