Observations of Lyman-alpha emitting galaxies (LAEs) provide clues to the formation and evolution of star forming galaxies, and the large-scale structure of the Universe. Zheng and Cen will simulate the Lyman-alpha emission for hundreds of simulated galaxies. This work will establish a theoretical framework for interpreting LAE observations. The team is actively engaged in public outreach. Cen participates in a program at the Rose-Hayden Planetarium of the American Museum of Natural History in New York City. Zheng will work with the Refugees Exploring the Foundations of Under Graduate Education in Science program at the University of Utah. The program serves under-represented middle and high school students through hands-on science workshops and activities designed to prepare the students for college.Zheng and Cen will employ a high-resolution cosmological hydrodynamic galaxy formation simulation combined with an efficient Monte Carlo Lyman-alpha radiative transfer code to investigate Lyman-alpha emission properties of LAEs and the clustering of LAEs. Observational astronomers will use this theoretical framework to interpret Lyman-alpha emission from circumgalactic and intergalactic media, investigate the role of LAEs during the epoch of reionization, and test the use of LAEs to map large scale structure. The simulated data will also be used to refine LAE detection algorithms, evaluate systematic uncertainties in on-going and future LAE surveys, and provide simulated data to test survey analysis pipelines.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.

Lyman-Alpha排放星系（LAES）的观察为恒星形成星系的形成和演变提供了线索，以及宇宙的大规模结构。 Zheng和Cen将模拟数百个模拟星系的Lyman-Alpha发射。这项工作将建立一个理论框架来解释LAE观察。该团队积极参与公共宣传。 CEN参加了纽约市美国自然历史博物馆的玫瑰海登天文馆的计划。郑将与难民合作，探讨犹他大学科学教育研究生教育计划的基础。 The program serves under-represented middle and high school students through hands-on science workshops and activities designed to prepare the students for college.Zheng and Cen will employ a high-resolution cosmological hydrodynamic galaxy formation simulation combined with an efficient Monte Carlo Lyman-alpha radiative transfer code to investigate Lyman-alpha emission properties of LAEs and the clustering of LAEs.观察天文学家将使用这个理论框架来解释与海洋乳酸和播种培养基中的Lyman-Alpha发射，研究LAE在电离时期的作用，并测试LAE在绘制大规模结构的使用。模拟数据还将用于完善LAE检测算法，评估正在进行和未来的LAE调查中的系统不确定性，并提供模拟数据以测试调查分析管道。该奖项反映了NSF的法定任务，并通过评估该基金会的知识点功能和广泛的影响来评估NSF的法定任务。
