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.

星系的分布仍然是 以及对起源和发展理论的初步检验 宇宙中的结构。 动力学和位置信息- 红色的星系分布中所包含的元素 移位空间仍然是我们唯一能处理底层的好方法 质量分布。 这项研究将扩展我们的知识 非常遥远的星系分布到一个非常大的 度，大约是现有红移数量的两倍 宇宙学模型的构建和测试。 该计划将由该组织的成员执行， 第一次发现非常大规模的不均匀性， 诗，建立在以前的NSF资助下支持的工作， 多目标纤维系统的形式， 30个或更多的星系的光谱。 这 将允许测量大约20，000个红移，分布在 超过800平方度的天空。
