This award is funded in whole or in part under the American Rescue Plan Act of 2021 (Public Law 117-2). Rebecca Levy is awarded an NSF Astronomy and Astrophysics Postdoctoral Fellowship to conduct a program of research and education at the University of Arizona. Levy will undertake radio and optical observations of nearby galaxies to understand the distribution of ionized regions and molecular gas within star-forming regions at scales ranging from individual protostars to galactic winds. Results from this study will allow astronomers to understand how processes controlling star formation influence the spatial and temporal evolution of galaxies. For the education component of her project, Levy will conduct a weekly program to develop the scientific identities and confidence of tribal middle school students.This project will elucidate how the processes of star formation and stellar feedback shape galaxies in the local Universe. Measurements of the sizes and structures of HII regions around massive young forming clusters in NGC 253, in concert with a previous molecular gas analysis, will probe the impact of the clusters on shaping their environment and powering the nuclear starburst. In M82, the observations will trace the bulk of the neutral material and reveal the cooling and fate of the wind, answering fundamental questions about the state of the largest mass reservoir in the wind.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.

该奖项全部或部分根据2021年美国救援计划法案（公法117-2）资助。丽贝卡·利维被授予NSF天文学和天体物理学博士后奖学金，在亚利桑那大学进行研究和教育计划。 Levy将对附近星系进行无线电和光学观测，以了解从单个原恒星到星系风尺度上的恒星形成区域内电离区和分子气体的分布。 这项研究的结果将使天文学家了解控制星星形成的过程如何影响星系的时空演化。 对于她的项目的教育部分，利维将进行每周一次的计划，以发展部落中学生的科学身份和信心。这个项目将阐明星星形成和恒星反馈的过程如何塑造星系在本地宇宙。测量NGC 253中大规模年轻形成的星团周围HII区域的大小和结构，与之前的分子气体分析相结合，将探测星团对塑造其环境和为核星爆提供动力的影响。在M82中，观测将追踪大部分中性物质，揭示风的冷却和命运，回答有关风中最大质量水库状态的基本问题。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
