项目摘要

One of the most prominent and exciting challenges in fundamental physics is understanding the nature of dark matter, which accounts for 85% of all matter throughout the known Universe. Dark matter plays a crucial role in forming galaxies, galaxy clusters, and larger structures of matter through its gravitational effects on ordinary particles. A key question is whether or not dark matter experiences any forces beyond gravity. Dedicated experimental efforts to search for new dark matter physics have thus far produced null results, prompting the development of new theoretical ideas and detection techniques. The PI's research program will tackle the dark matter problem at the intersection of cosmology and particle physics, using cosmological and astrophysical observations to study the microscopic properties of dark matter. Such observations have emerged as a powerful probe of dark matter, due to their increase in precision and sensitivity over recent years. The PI's research will provide foundational work for future dark matter analyses, in preparation for potential new discoveries as next-generation instruments and surveys begin operations in the upcoming decade. In conjunction with research, this program incorporates the mentoring and training of students and postdocs, who are poised become the future scientific leaders of the field.This research will study the impact of dark matter interactions with ordinary particles throughout cosmic time. These interactions affect the formation of, for example, the cosmic microwave background and small-scale structure, enabling the opportunity to search for new dark matter physics using cosmological and astrophysical observations. This research will pursue new avenues to bridge theoretical models and observational techniques to study dark matter. It will involve the development of sophisticated tools to perform joint analyses using multiple datasets.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.

基本物理学中最突出和最令人兴奋的挑战之一是了解暗物质的性质，暗物质的本质占已知宇宙中所有物质的85％。暗物质通过其对普通颗粒的重力影响在形成星系，星系簇和更大物质结构中起着至关重要的作用。一个关键的问题是暗物质是否经历了重力以外的任何力量。迄今为止，搜索新的暗物质物理学的专门实验努力已经产生了无效的结果，从而促使了新的理论思想和检测技术的发展。 PI的研究计划将使用宇宙学和天体物理学观测来研究暗物质的微观特性，以解决宇宙学和粒子物理学交集的暗物质问题。由于近年来，这种观察结果已成为对暗物质的强大探针。 PI的研究将为未来的暗物质分析提供基本工作，以准备在接下来的十年开始下一代工具和调查开始运营时，为潜在的新发现做准备。与研究结合，该计划结合了对学生和博士后的指导和培训，他们有望成为该领域的未来科学领导者。这项研究将研究整个宇宙时间中暗物质相互作用与普通颗粒的影响。这些相互作用会影响例如宇宙微波背景和小规模结构的形成，从而有机会使用宇宙学和天体物理学观测来寻找新的暗物质物理。这项研究将追求新的途径，以弥合理论模型和观察技术来研究暗物质。它将涉及使用多个数据集执行联合分析的复杂工具的开发。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的影响评估标准通过评估来获得支持的。
