A Redshift Survey from Las Campanas

星系的分布仍然是宇宙结构起源和增长理论的主要动机和主要检验。星系在红移空间中的分布所包含的动力学和位置信息仍然是我们对潜在质量分布的唯一好的把握。这项研究将在很大程度上扩展我们对非常遥远星系分布的了解，大约将用于构建和测试宇宙模型的红移数量增加一倍。这个项目将由第一个发现宇宙中超大尺度非均质性的小组成员执行，它建立在先前由美国国家科学基金会资助的多物体光纤系统的基础上，该系统可以在短短两小时内获得30个或更多的星系的良好光谱。这将允许在未来两年内测量分布在800平方度天空上的大约20,000个红移。

The distribution of galaxies remains both the primary motivation and the primary test of theories of the origin and growth of structure in the universe. The dynamical and positional informa- tion which is contained in the distribution of galaxies in red- shift space is still the only good handle we have on the underly- ing mass distribution. This research will extend our knowledge of the distribution of very distant galaxies to a very large degree, approximately doubling the number of redshifts available for the construction and testing of cosmological models. This program, to be carried out by members of the group which first discovered very large scale inhomogeneities in the uni- verse, builds on work supported under a previous NSF grant in the form of a multi-object fiber system which permits obtaining thirty or more good spectra of galaxies in only two hours. This will permit the measurement of some 20,000 redshifts, distributed over 800 square degrees of sky over the next two years.
