This award funds the research activities of Professor Vera Gluscevic at the University of Southern California (USC). Particles that represent the building blocks of the visible universe account for merely 15% of all matter known to exist. The rest is dark matter, invisible to telescopes, and dominating virtually all galaxies. Dark matter cannot be explained by any known particles; its physical nature is yet to be understood. At the same time, dark matter has shaped the Universe throughout its history, leaving clues in observational data. As part of her research, Professor Gluscevic will use a combination of cosmological observations, computer simulations, and analytic theory to probe how dark matter might interact with normal matter, and to understand how these interactions might affect observational data. This research advances the national interest by promoting the progress of science, in particular our understanding of the building blocks of the Universe in which we live. This work also has significant broader societal impacts. Professor Gluscevic will engage several students and a postdoc in research projects related to this proposal, providing them with essential training in the field. She will also start a dedicated lecture series within the Women in Physics program at USC, to help promote diversity, equity, and inclusion in STEM, enhance networking opportunities, and strengthen the sense of belonging amongst women in Physics and Astronomy.More technically, the key objective of Professor Gluscevic’s work is to develop, implement, and apply a novel comprehensive theoretical framework for probing dark-matter particle interactions with baryons, using a variety of observations. In particular, this work will enable consistent computation of the effects of dark matter-baryon interactions on various cosmological observables, improve treatment of theoretical uncertainty in calculation of signals within interacting-dark-matter cosmology, and provide new limits on dark-matter theory. Development of the proposed framework at present is critical, in preparation for analyses of data from the next generation of cosmological and astrophysical surveys.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.

该奖项为南加州大学（USC）的Vera Gluscevic教授的研究活动提供资金。代表可见宇宙的构件的粒子仅占已知存在的所有物质的15％。其余的是暗物质，对望远镜看不见，几乎所有星系占主导地位。暗物质不能用任何已知颗粒来解释。它的物理性质尚未被理解。同时，暗物质在整个历史上都塑造了宇宙，从而使群集在观察数据中。作为她研究的一部分，Gluscevic教授将使用宇宙学观察，计算机模拟和分析理论的结合来探测暗物质如何与正常物质相互作用，并了解这些相互作用如何影响观察数据。这项研究通过促进科学的进步，特别是我们对我们所居住的宇宙的基础的理解来推动国家利益。这项工作还具有重大的广播社会影响。 Gluscevic教授将与几个学生和一个博士后与该提案有关的研究项目，从而为他们提供了该领域的基本培训。她还将在南加州大学的物理学女性计划中启动专门的讲座系列，以帮助促进多样性，公平性和包容性，增强网络机会，并增强妇女在物理和天文学领域的归属感。从技术上讲，Gluscevic教授的工作的主要目的是使用新颖的框架进行综合框架来探讨vertions vorthers的互动，以实现跨越的范围。特别是，这项工作将能够一致地计算暗物质 - 巴里昂相互作用对各种宇宙学观察的影响，改善对相互作用 - 漆黑宇宙学中信号计算的理论不确定性的处理，并为深色摩擦理论提供新的限制。目前，目前提出的框架的开发是至关重要的，为分析下一代宇宙学和天体物理调查的数据分析。该奖项反映了NSF的法定任务，并被认为是通过基金会的智力优点和更广泛的影响来通过评估来获得的支持。
