摘要
VANDELS 是利用 ESO 甚大望远镜 (VLT) 上的 VIMOS 光谱仪对高红移星系进行的一项独特深度光谱巡天。该巡天在以 CANDELS UDS 和 CDFS 场为中心、总面积约 0.2 平方度的区域内，对红移区间 1.0 < z < 7.0 内的约 2100 个星系获得了超深光学 (0.48 < lambda < 1.0 micron) 光谱。基于精确的光度红移预选，VANDELS 观测的星系中有 85% 被选为 z>=3。利用翻新后的 VIMOS 光谱仪的红色灵敏度，该巡天的基本目标是提供高信噪比光谱，以便通过详细的吸收线研究测量关键物理性质，如星族年龄、质量、金属丰度和外流速度。利用旨在产生近似恒定信噪比 (20 < t_int < 80 小时) 的积分时间，VANDELS 巡天的目标为：a) 2.4 < z < 5.5 处的明亮恒星形成星系；b) 1.0 < z < 2.5 处的大质量宁静星系；c) 3.0 < z < 7.0 处较暗的恒星形成星系；d) X 射线/Spitzer 选活动星系核及 Herschel 探测到的星系。通过观测两个具有极佳多波段成像数据的河外巡天场，VANDELS 将产生一个独特的遗产数据集，用于探索支撑高红移星系演化的物理学。在本文中，我们概述了旨在支持首次 ESO 公共数据发布科学利用的 VANDELS 巡天，重点关注科学动机、巡天设计和目标选择。
