摘要:

我们描述了VIPERS(VIMOS公共河外红移巡天)的结构和一般特征。这个“大方案”一直在使用欧洲南方天文台甚大望远镜,目的是建立一个大约100,000个i_{AB} <22.5和0.5<z<1.5的星系的光谱样本。该调查覆盖了CFHTLS范围内W1和W 4区域内约24 deg^2的总面积。VIPERS的设计目的是解决大尺度结构和星系演化方面的广泛问题,这要归功于体积(~ 5 x 10^7 h^{-3} Mpc ^3)和采样率(~ 40%)的独特组合,可与当地宇宙的最先进调查相媲美,以及广泛的多波段光学和近红外测光。本文介绍了巡天的设计、源目录的选择和分光观测的发展。我们详细讨论了从项目的不同组成部分的组合结果的整体选择功能。这包括由母测光样本和光谱仪器足迹产生的掩模,以及考虑采样和观测成功率所需的权重。使用目录的53,608星系红移组成即将到来的VIPERS公共数据发布1(PDR-1),我们提供了光谱数据的质量的第一次评估。受益于该数据集的大小和详细采样的结合,我们得出结论,展示了一张前所未有的详细地图,显示了50亿至80亿年前星系的大规模分布。[删节]

英文摘要:

We describe the construction and general features of VIPERS, the VIMOS Public Extragalactic Redshift Survey. This `Large Programme' has been using the ESO VLT with the aim of building a spectroscopic sample of ~100,000 galaxies with i_{AB}<22.5 and 0.5<z<1.5. The survey covers a total area of ~24 deg^2 within the CFHTLS-Wide W1 and W4 fields. VIPERS is designed to address a broad range of problems in large-scale structure and galaxy evolution, thanks to a unique combination of volume (~ 5 x 10^7 h^{-3} Mpc^3) and sampling rate (~ 40%), comparable to state-of-the-art surveys of the local Universe, together with extensive multi-band optical and near-infrared photometry. Here we present the survey design, the selection of the source catalogue and the development of the spectroscopic observations. We discuss in detail the overall selection function that results from the combination of the different constituents of the project. This includes the masks arising from the parent photometric sample and the spectroscopic instrumental footprint, together with the weights needed to account for the sampling and the success rates of the observations. Using the catalogue of 53,608 galaxy redshifts composing the forthcoming VIPERS Public Data Release 1 (PDR-1), we provide a first assessment of the quality of the spectroscopic data. Benefiting from the combination of size and detailed sampling of this dataset, we conclude by presenting a map showing in unprecedented detail the large-scale distribution of galaxies between 5 and 8 billion years ago.
