Dark matter is the unknown mass that makes up the cosmic foundation of the Universe. This research in theoretical physics will explore how dark matter's microscopic particle dynamics can shape the structure of galaxies and other astronomical observables. Observations, in turn, will be used to constrain and determine dark matter's unknown properties. Questions to be addressed include: Do dark matter particles interact with one another through any forces beyond gravity? If so,what types of forces are allowed when confronted with observations spanning the smallest galaxies to the large scale structure of the Universe?

暗物质是未知的质量，构成了宇宙的宇宙基础。这项理论物理研究将探索暗物质的微观粒子动力学如何塑造星系和其他天文观测对象的结构。反过来，观测将被用来约束和确定暗物质的未知属性。要解决的问题包括：暗物质粒子是否通过引力以外的任何力相互作用？如果是这样的话，当面对从最小的星系到宇宙的大尺度结构的观测时，允许哪些类型的力？
