This is a collaborative project, lead 0607686/Burles, non-leads 0607541/Eisenstein and 0607701/Blanton.This project represents the first stage of the PRIsm MUlti-object Survey (PRIMUS), whose ultimate goal is to map a large volume of the Universe around redshift one, a volume comparable to those already mapped in the local Universe. Low-resolution prism spectroscopy in the large field of view allowed by the 6.5m Magellan telescope at Las Campanas, Chile, determines redshifts for faint galaxies at much higher rates than previously possible. This phase covers commissioning the instrument and obtaining about 125,000 galaxy redshifts in regions of the sky with other deep data already available. It will enable measurement of the growth of galaxies, the environmental dependence of morphology, and the correlation function, all as a function of time. In addition to providing a state-of-the-art sample, the PRIMUS commissioning project will test plans for the full PRIMUS.Both raw and reduced data will be made public as they become available, providing a valuable resource to the astrophysics community. If successful, this project is also likely to influence the design of future large surveys. Since redshifts turn two-dimensional images into three-dimensional maps, the project will also explore the outreach and teaching tools that can be created from cosmic maps of such a tremendous volume of the Universe. Graduate student involvement is critical, and undergraduate involvement will be encouraged.

这是一个协作项目，铅0607686/burles，非领导0607541/艾森斯坦和0607701/blanton.Blanton.THIS。该项目代表了Prism Multi-Object调查（Primus）的第一个阶段，其最终目标是在Redshift Oneploble的宇宙周围绘制大量宇宙的最终目标，以绘制那些本地宇宙的宇宙，以与本地的宇宙相比，以供众所周知。 智利拉斯坎帕纳斯（Las Campanas）650万麦哲伦望远镜允许的较大视野中的低分辨率棱镜光谱法确定了微弱星系的红移，比以前更高。 该阶段涵盖了调试工具，并在天空地区获得了约125,000个星系红移，并拥有其他深度数据。 它将能够测量星系的生长，形态的环境依赖性以及相关函数，都是时间的函数。 除了提供最先进的样本外，Primus调试项目还将测试完整的Primus的计划。随着它们的可用，原始数据和减少的数据都将公开，为天体物理学社区提供了宝贵的资源。 如果成功，该项目也可能会影响未来大型调查的设计。 由于红移将二维图像变成三维图，因此该项目还将探索可以从如此巨大的宇宙中创建的外展和教学工具。 研究生的参与至关重要，将鼓励本科参与。
