项目摘要

This CAREER award funds the research activities of Professor Tien-Tien Yu at the University of Oregon. After many years of increasingly compelling observational evidence, scientists have come to believe that most of the matter in the Universe is unlike the ordinary matter that we see and interact with every day. This matter is called “dark matter” as it cannot be observed directly. Instead, the existence of dark matter is deduced through its gravitational effects on astrophysical objects such as stars and galaxies, which hints that it could be either a new type of particle or several different types of particles that together comprise a dark sector. The fact that dark matter interacts gravitationally suggests that it has a mass, but the range of possible dark-matter masses is unknown. In recent years, research has facilitated an explosion of ideas and experimental efforts aimed at searching for dark-sector candidates across a wide range of masses. In anticipation of the plethora of data and potential discoveries that will be enabled by these experimental efforts, Professor Yu will conduct an original research program focused on searching for and understanding a wide range of dark-sector theories in which she will elucidate the possible interpretations of a putative experimental signal. Research on dark-sector physics advances the national interest by promoting the progress of science in one of its most fundamental directions: the discovery and understanding of new physical law.More technically, Professor Yu will unravel the dependence of dark-matter direct-detection rates on astrophysical uncertainties by applying a variety of different astrophysical models to dark matter-electron scattering calculations. In addition, she will develop a framework for presenting dark matter-electron scattering rates in a manner that is independent of the underlying astrophysical model, thereby circumventing the limitations on interpretation set by astrophysical uncertainties. She will also uncover the potential of sub-GeV dark matter experiments by exploring the signatures of a broad range of theoretical models. Her work will allow for more robust interpretations of the experimental data and provide the foundational research for potential transformative discoveries. She will also explore in more detail the interplay between dark matter and gravitational waves, starting with a thorough calculation of neutron-star superradiance. This project is also envisioned to have significant broader impacts. Professor Yu will integrate her research and educational goals by developing a unique scientific communication program that aims to increase the accessibility of complex physics concepts through visual media. Comics and visual media provide a unique and accessible format to engage diverse audiences. Professor Yu will develop a new program in visual scientific communication through collaboration with the University of Oregon’s strong Comic Studies program. By integrating visual media as the primary framework, this program aims to build skills and attitudes among underrepresented minority students in physics to enhance retention while simultaneously providing engaging, informal STEM education to a broad audience including humanities and design students.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.

该职业奖资助俄勒冈大学余添添教授的研究活动经过多年越来越令人信服的观测证据，科学家们开始相信宇宙中的大多数物质与我们看到和看到的普通物质不同。这种物质被称为“暗物质”，因为它无法直接观察到，而是通过其对恒星和星系等天体物理物体的引力作用来推断，这暗示它可能是一种物质。新的暗物质相互作用的事实表明它具有质量，但暗物质质量的范围目前尚不清楚。旨在广泛寻找暗区候选者的想法和实验努力的爆发预计这些实验工作将带来大量数据和潜在发现，于教授将开展一项原创研究计划，重点关注。寻找和理解广泛的她将在其中阐明对假定的实验信号的可能解释，通过促进科学在其最基本方向之一的进步来促进国家利益：发现和理解新物理学。从技术上讲，于教授将通过将各种不同的天体物理模型应用于暗物质电子散射计算来揭示暗物质直接探测率对天体物理不确定性的依赖性。此外，她还将开发一个框架。她还将以独立于基础天体物理模型的方式研究暗物质-电子散射率，从而规避天体物理不确定性对解释的限制，她还将通过探索广泛范围的特征来揭示亚GeV暗物质实验的潜力。她的工作将为实验数据提供更可靠的解释，并为潜在的变革性发现提供基础研究，她还将从彻底的计算开始，更详细地探索暗物质和引力波之间的相互作用。预计该项目将通过开发一个独特的科学传播项目来整合她的研究和教育目标，旨在通过视觉媒体提高复杂物理概念的可理解性。余教授将通过与俄勒冈大学强大的漫画研究项目合作，开发一个新的视觉科学传播项目，将视觉媒体作为主要框架，旨在培养技能。以及代表性不足的少数族裔学生的态度物理以提高记忆力，同时为包括人文和设计专业学生在内的广大受众提供引人入胜的非正式 STEM 教育。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
