Christopher Faesi is awarded an NSF Astronomy and Astrophysics Postdoctoral Fellowship to conduct a program of research and education at the University of Massachusetts, Amherst. Faesi will undertake an extensive observational program to study Giant Molecular Clouds (GMCs)---the birthplaces of stars---in a large sample of nearby galaxies. Studying how the properties of GMCs change with the environmental conditions within galaxies will allow astronomers to understand how those conditions influence star formation. Alongside this research, Faesi will develop a series of lesson plans to introduce modern astronomical research into undergraduate classrooms. Faesi will measure GMC properties across a range of environments and develop methods to calibrate star formation rates at GMC scales in nearby galaxies. This will allow a better understanding of the global relationship between stars and interstellar gas in galaxies. For the educational component of his work, Faesi will develop a program to expose undergraduate students to astronomical research by implementing lesson plans involving digestible summaries of recent research articles, and he will assess how this exposure affects student retention, interest, and success in science.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

克里斯托弗Faesi被授予NSF天文学和天体物理学博士后奖学金，在阿默斯特的马萨诸塞州大学进行研究和教育计划。 Faesi将进行一项广泛的观测计划，以研究附近星系的大样本中的巨型分子云（GMC）-恒星的诞生地。 研究GMC的性质如何随着星系内的环境条件而变化，将使天文学家了解这些条件如何影响星星的形成。 除了这项研究，Faesi还将制定一系列课程计划，将现代天文学研究引入本科课堂。Faesi将在一系列环境中测量GMC特性，并开发方法来校准附近星系中GMC尺度下的星星形成速率。 这将使我们更好地了解恒星和星系中星际气体之间的全球关系。 对于他工作的教育部分，Faesi将开发一个计划，通过实施包含最近研究文章的可消化摘要的教案，让本科生接触天文学研究，他将评估这种接触如何影响学生的保留率、兴趣、该奖项反映了NSF的法定使命，并被认为值得通过使用基金会的智力价值和更广泛的影响审查标准。
