This research team will carry out an extensive theoretical and computational investigation into the nature of dark matter. Using computer simulations to understand galaxy formation within this Fuzzy Dark Matter (FDM) model, they will predict observational signatures and large-scale statistics, and constrain the value for the mass of the FDM particle. This will allow FDM to be verified, constrained, or excluded with existing or new observations. This study directly affects other research, including the design of next-generation experiments searching for direct evidence of a possible dark matter particle. The work will connect women and under-represented minority students to mentorship and research projects, helping to develop a diverse, globally competitive STEM workforce, and provide curricular tools to high school teachers, to engage a large audience of potential STEM students. FDM is a physically motivated model that could solve the small-scale astrophysical challenges faced by the prevailing cold dark matter interpretation. It predicts many small-scale effects that might be observable. This project will dramatically improve our theoretical understanding of the nonlinear behavior of ultra-light scalar fields in the Universe. Because analytic theory does not capture all the important physical processes, these state-of-the-art numerical simulations will establish new ways for observations to constrain the FDM model. They will probe the small-scale dynamics of dark matter, distinguish between models, and possibly establish the nature of dark matter. The work will generate open-source tools and products which can be used to interpret observations of high-redshift galaxies or the astrometry of Milky Way stars.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.

该研究团队将对暗物质的性质进行广泛的理论和计算调查。使用计算机模拟来了解模糊暗物质（FDM）模型中的星系形成，他们将预测观察性特征和大规模统计，并限制FDM粒子质量的值。这将允许使用现有或新观察结果对FDM进行验证，约束或排除。这项研究直接影响了其他研究，包括设计下一代实验，以寻找可能的暗物质粒子的直接证据。这项工作将把妇女和代表性不足的少数族裔学生与指导和研究项目联系起来，帮助发展多样化的全球竞争性STEM劳动力，并为高中教师提供课程工具，以吸引大量潜在的STEM学生的受众。 FDM是一个有力动机的模型，可以解决盛行的冷暗物质解释所面临的小规模天体物理挑战。它预测了许多可能可观察到的小规模效应。该项目将显着提高我们对宇宙中超光标量字段非线性行为的理论理解。由于分析理论并未捕获所有重要的物理过程，因此这些最先进的数值模拟将为观察限制FDM模型建立新的方法。他们将探测暗物质的小规模动态，区分模型，并可能建立暗物质的性质。这项工作将生成开源工具和产品，可用于解释高红移星系的观察或银河系明星的天文标准。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛影响的评估标准来通过评估来进行评估的。
