VANDELS是ESO甚大望远镜（VLT）上的VIMOS摄谱仪对高红移星系进行的一次独特的深度光谱调查。该巡天获得了红移区间1.0 ≤ z ≤ 7.0内的2100个星系的超深光学（0.48 < λ < 1.0 μm）光谱，总面积为10.2平方度，以CANDELS超深巡天和钱德拉深场南场为中心。根据精确的光度红移预选，范德尔望远镜所瞄准的星系中有85%被选为z ≥ 3。利用翻新的VIMOS摄谱仪的红色灵敏度，调查的基本目的是提供必要的高信噪比光谱，以测量关键的物理特性，如恒星的人口年龄，质量，金属丰度和流出速度，从详细的吸收线研究。使用计算的积分时间以产生近似恒定的信噪比（20 < tint< 80 h），VANDELS调查的目标是：（a）2.4 ≤ z ≤ 5.5的明亮恒星形成星系，（B）1.0 ≤ z ≤ 2.5的大质量静止星系，（c）3.0 ≤ z ≤ 7.0的较暗恒星形成星系，（d）X射线/斯皮策选择的活动星系核和赫歇尔探测的星系。通过用极好的多波长成像数据瞄准两个河外勘测场，VANDELS将产生一个独特的遗留数据集，用于探索支撑高红移星系演化的物理学。在本文中，我们提供了一个概述的VANDELS调查，旨在支持科学利用的第一个ESO公开数据发布，重点是科学的动机，调查设计和目标选择。
VANDELS is a uniquely deep spectroscopic survey of high-redshift galaxies with the VIMOS spectrograph on ESO’s Very Large Telescope (VLT). The survey has obtained ultradeep optical (0.48 < λ < 1.0 μm) spectroscopy of ≃2100 galaxies within the redshift interval 1.0 ≤ z ≤ 7.0, over a total area of ≃0.2 deg2 centred on the CANDELS Ultra Deep Survey and Chandra Deep Field South fields. Based on accurate photometric redshift pre-selection, 85 per cent of the galaxies targeted by VANDELS were selected to be at z ≥ 3. Exploiting the red sensitivity of the refurbished VIMOS spectrograph, the fundamental aim of the survey is to provide the high-signal-to-noise ratio spectra necessary to measure key physical properties such as stellar population ages, masses, metallicities, and outflow velocities from detailed absorption-line studies. Using integration times calculated to produce an approximately constant signal-to-noise ratio (20 < tint< 80 h), the VANDELS survey targeted: (a) bright star-forming galaxies at 2.4 ≤ z ≤ 5.5, (b) massive quiescent galaxies at 1.0 ≤ z ≤ 2.5, (c) fainter star-forming galaxies at 3.0 ≤ z ≤ 7.0, and (d) X-ray/Spitzer-selected active galactic nuclei and Herschel-detected galaxies. By targeting two extragalactic survey fields with superb multiwavelength imaging data, VANDELS will produce a unique legacy data set for exploring the physics underpinning high-redshift galaxy evolution. In this paper, we provide an overview of the VANDELS survey designed to support the science exploitation of the first ESO public data release, focusing on the scientific motivation, survey design, and target selection.
