Calar Alto深度成像调查（CADIS）采用三个宽频带（B，R，K）和多达13个中频带(R = λ/Δλ= 25…50)通过成像法布里-普氏干涉仪进行光谱扫描（R≃450）。本次调查将覆盖10个油田，即：总面积0.3□°。虽然主要设计用于探测各种中间（z= 0.2…1.4）和非常高红移（z= 4.7, 5.7, 6.5）的微弱发射线星系，但它的多色策略也将允许探测和分类我们银河系中数百个早期星系，微弱的qso和极其微弱的恒星。这篇文章概述了巡天的概念和主要目标，然后重点介绍了对“原始”Ly-α发射星系atz > 5的期望和初步结果。关于中间红移暗场星系的数据分析和初步结果的更多细节，见Fockenbrocket等人和Thommeset等人对这些会议的贡献。
The Calar Alto Deep Imaging Survey (CADIS) employs a combination of deep exposures in three broad bands (B,R,K) and up to 13 medium bands (R = λ/Δλ= 25... 50) with spectroscopic scans through an imaging Fabry-Pérot-Interferometer (R≃ 450). The survey will cover 10 fields of > 100□′,i.e.a total area of 0.3 □°. Although primarily designed to detect faint emission line galaxies at various intermediate (z= 0.2 ...1.4) and very high redshifts (z= 4.7, 5.7, 6.5) its multi-color strategy will also allow the detection and classification of hundreds of early type galaxies, faint QSOs, and extremely faint stars in our Galaxy. This contribution outlines the survey concept and its principal goals and then focuses on the expectations and first results of the search for “primeval” Ly-α emitting galaxies atz≳ 5. More details about the data analysis and first results on faint field galaxies at intermediate redshift are presented in the contributions by Fockenbrocket al.and Thommeset al.to these proceedings.
