摘要
宇宙组装近红外深空河外星系遗留巡天 (CANDELS) 旨在记录大约红移 (z) 范围在 8--1.5 内的星系演化第一个三分之一的时期。它将使用哈勃空间望远镜上的三个独立相机，从中紫外到近红外波段对 >250,000 个遥远星系进行成像，并将寻找和测量 z>1.5 处的 Ia 型超新星，以检验其作为宇宙学可标准化烛光的准确性。选定了五个首要的多波长天区，每个天区都有广泛的辅助数据。使用五个广泛分离的场可以减轻宇宙方差，并提供在 z \approx 2 时恒星质量低至 10^9 M_\odot 的统计稳健且完整的星系样本，在 z \approx 8 时达到星系紫外光度函数 (UVLF) 的拐点。该巡天覆盖约 800 arcmin^2，分为两部分。CANDELS/深场巡天 (5\sigma 点源极限 H=27.7 mag) 覆盖 GOODS-N 和 GOODS-S 内的 \sim 125 arcmin^2。CANDELS/广场巡天包括 GOODS 和另外三个场 (EGS, COSMOS 和 UDS)，并将整个区域覆盖至 5\sigma 点源极限 H \gtrsim 27.0 mag。结合哈勃超深场，该策略创造了一种三层“婚礼蛋糕”方法，这已被证明对河外星系巡天非常有效。巡天数据是非专有的，可用于广泛的科学研究。在本文中，我们描述了该巡天的基本动机、CANDELS 团队的科学目标及由此产生的观测要求、场选择和几何形状，以及观测设计。哈勃数据处理和产品在另一篇配套论文中描述。
