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.

这是一个合作项目，Lead 0607686/Burles，Non-Lead 0607541/Eisenstein和0607701/Blanton。这个项目代表了棱镜多目标调查(PRIMUS)的第一阶段，其最终目标是绘制红移一周围的大宇宙体积，这个体积与本地宇宙中已经绘制的体积相当。智利拉斯坎帕纳斯的6.5米麦哲伦望远镜所允许的大视场中的低分辨率棱镜光谱，以比以前可能的更高的速率确定了微弱星系的红移。这一阶段包括调试该仪器，并在已有其他深层数据的情况下，在天空区域获得约125,000个星系红移。它将使测量星系的生长、形态的环境依赖性和关联函数成为可能，所有这些都是时间的函数。除了提供最先进的样本外，Primus调试项目还将测试完整PRIMU的计划。原始数据和简化数据将在可用时公开，为天体物理界提供宝贵的资源。如果成功，该项目还可能影响未来大型调查的设计。由于红移将二维图像转化为三维地图，该项目还将探索可以从如此巨大的宇宙体积的宇宙地图中创建的扩展和教学工具。研究生的参与是至关重要的，我们将鼓励本科生的参与。
