The goal of this program is to model the ultraviolet light emitted during the early universe when the first stars, galaxies, and black holes were being formed. This is one of the last epochs of the universe to remain unexplored. Broader impacts of the program include training of graduate students, and mentoring of groups of freshman undergraduates from communities that are underrepresented in the physical sciences that are participating in the Pre-MAP program at the University of Washington. Furthermore, this award supports three paid undergraduate summer internships, which will be filled either by the pre-MAP students or astronomy majors at the University of Washington.This research will improve modeling of fluctuating ionizing backgrounds and the Ly-alpha forest around the epoch of reionization to better understand the process and sources of reionization. In addition, the program plans to provide a flexible, publicly available ionizing background computer code.

该计划的目标是模拟宇宙早期发出的紫外线，当时第一批恒星，星系和黑洞正在形成。这是宇宙中最后一个未被探索的时代之一。该计划的更广泛的影响包括研究生的培训，以及指导来自参与华盛顿大学前MAP计划的物理科学代表性不足的社区的大一本科生群体。 此外，该奖项还支持三个带薪的本科暑期实习，这将由华盛顿大学的前MAP学生或天文学专业的学生填补。这项研究将改善波动的电离背景和Ly-alpha森林的再电离时代周围的建模，以更好地了解再电离的过程和来源。此外，该计划还计划提供一个灵活的、公开可用的电离背景计算机代码。
