Strauss, Michael 96-16901 Dr. Strauss plans to combine observational data and theoretical analyses to constrain the standard model for the evolution of the universe and its formation of structure. The observations include two all-sky photometric and spectroscopic surveys of galaxies to measure the large-scale bulk flow of galaxies. Also planned is a detailed statistical comparison of the large-scale distribution of galaxies of different morphological types to constrain physical models for the relatite distribution of galaxies and dark matter. The final portions of the research are to compare the observed galaxy density and velocity fields, to test the gravitational instability paradigm and to constrain the Cosmological Density Parameter.

Strauss, Michael 96-16901 施特劳斯博士计划结合观测数据和理论分析来约束宇宙演化及其结构形成的标准模型。 这些观测包括对星系进行两次全天光度和光谱测量，以测量星系的大尺度整体流。 还计划对不同形态类型星系的大尺度分布进行详细的统计比较，以约束星系和暗物质相关分布的物理模型。 研究的最后部分是比较观测到的星系密度和速度场，测试引力不稳定范式并约束宇宙学密度参数。
