Large Scale Structure in the mildly nonlinear regime

这一理论计划将提高我们对宇宙中大尺度结构(如星系团)形成的理解，并利用这种理解为观测研究得出的宇宙学模型提供约束。这项工作的更广泛影响包括培训一名博士后研究员，为成人和小学和中学举办公开讲座，接受媒体采访，包括针对拉美裔观众的采访，以及在老年中心举办一系列讲座。Zaldriaga将开发一个新的理论和统计框架，结合两种最先进的技术：提供理论基础的分析场论方法，以及以有效和统计准确的方式将理论与观测对峙的计算和统计技术。这项工作将有助于未来解释来自大型天气观测望远镜(LSST)的数据。

This theoretical program will improve our understanding of the formation of large-scale structures in the universe such as galaxy clusters, and use this understanding to provide constraints on cosmological models derived from observational studies. Broader impacts of the work include training of a postdoctoral researcher, public lectures both for adults and in primary and middle schools, interviews in the media including those targeted to Hispanic audiences, and a lecture series at a senior citizen center.Dr. Zaldarriaga will develop a new theoretical and statistical framework combining two state-of-the-art techniques: analytical field theory methods that provide a theoretical foundation, and computational and statistical techniques that confront theory with observations in an efficient and statistically accurate way. The work will be useful in the future interpretation of data from the Large Synoptic Survey Telescope (LSST).
