0530095 SpergelThis Partnership for International Research and Education award will support a multi-institutional partnership between Princeton University, Rutgers University, the University of Pennsylvania, Catolica University (Chile) and the University of KwaZulu-Natal (South Africa) that will address many of the deepest and most pressing questions in cosmology: What is the mysterious dark energy that is the dominant form of energy in the universe? Where are most of the atoms in the universe? How do galaxies and their environments affect each other? These questions will be addressed by a detailed study of a 100 square-degree strip of the Southern sky. Our observations will focus on the universe when it was between 2 and 6 billion years old. The new Southern African Large Telescope (SALT, in South Africa) will be used to make four-color images of the strip. The Atacama Cosmology Telescope (ACT, in Chile) will make microwave maps of this strip. We will identify galaxy clusters in the strip and then use the SALT spectrograph to obtain ages and redshifts for galaxies in the clusters. The Magellan and Blanco telescopes, also based in Chile, will provide additional high-quality imaging data for a gravitational lensing survey, directly probing the distribution of mass in the survey region. By combining our microwave maps with space-based X-ray observations, we will be able to measure the temperature and distribution of gas and compare it to the spatial distribution of galaxies. An integrated analysis and numerical simulation effort will combine all of the data sets and extract constraints on the universe as a whole and on the evolution of galaxies and clusters.This ambitious program will build strong international collaborations based on the scientific talents of three major US astronomy and physics programs (Princeton, Rutgers, and the University of Pennsylvania) and of two Southern Hemisphere institutions, Catolica University (Chile) and the University of KwaZulu-Natal (South Africa). This novel multi-national effort will provide superb international scientific training for undergraduates, graduate students, postdoctoral researchers, and young faculty. Undergraduate students will engage in an 8-week international research experience at one of the two Southern Hemisphere sites. Graduate students will be paired with their peers at other partner institutions and will participate in weekly video and web teleconferences. Semi-annual summer schools and workshops (alternating between hemispheres) will introduce graduate students and postdoctoral researchers to cutting-edge technologies, new scientific results, and different cultures. Students, postdoctoral researchers and faculty from other ACT institutions in the UK, Mexico, and Canada will also participate in the summer school, thus broadening the international collaborative network. Postdoctoral researchers and faculty will also travel to South Africa and Chile to work with their colleagues on data collection, analysis, and synthesis. This project will not only enable an exciting scientific research program but will also train future leaders that are able to prosper in the global scientific environment.

0530095 SpergelThis国际研究和教育奖的合作伙伴关系将支持普林斯顿大学，拉格斯大学，宾夕法尼亚大学，卡塔利亚大学，智利大学（智利）和夸祖鲁 - 夸祖鲁 - 纳塔尔大学（南非）之间的多机构合作伙伴关系，这将解决最深刻的能源，这是众多的统治力量，这是统治的统治力：宇宙中的大多数原子在哪里？ 星系及其环境如何相互影响？这些问题将通过对南部天空的100平方度条的详细研究来解决。 我们的观察结果将重点放在2到60亿年之间的宇宙上。 新的南部非洲大型望远镜（南非的盐）将用于制作条纹的四色图像。 Atacama宇宙学望远镜（智利行为）将制作此条带的微波图。 我们将识别带状的星系簇，然后使用盐光谱仪获得簇中星系的年龄和红移。 同样位于智利的麦哲伦和Blanco望远镜将为重力透镜调查提供其他高质量的成像数据，直接探测调查区域中质量的分布。 通过将我们的微波图与空间X射线观测相结合，我们将能够测量气体的温度和分布，并将其与星系的空间分布进行比较。 An integrated analysis and numerical simulation effort will combine all of the data sets and extract constraints on the universe as a whole and on the evolution of galaxies and clusters.This ambitious program will build strong international collaborations based on the scientific talents of three major US astronomy and physics programs (Princeton, Rutgers, and the University of Pennsylvania) and of two Southern Hemisphere institutions, Catolica University （智利）和夸祖鲁 - 纳塔尔大学（南非）。 这项新颖的跨国努力将为本科生，研究生，博士后研究人员和年轻教师提供精湛的国际科学培训。 本科生将在两个南半球的一个地点之一从事8周的国际研究经验。研究生将与其他合作伙伴机构的同龄人配对，并将参加每周的视频和网络电视节目。 半年度的暑期学校和讲习班（半球之间的交替）将向研究生和博士后研究人员介绍尖端的技术，新的科学结果和不同的文化。 来自英国，墨西哥和加拿大其他ACT机构的学生，博士后研究人员和教师也将参加暑期学校，从而扩大国际合作网络。 博士后研究人员和教职员工还将前往南非和智利与同事一起进行数据收集，分析和综合。该项目不仅将启用令人兴奋的科学研究计划，而且还将培训能够在全球科学环境中繁荣发展的未来领导者。
