Research will be carried out in cosmology and theoretical elementary particle physics. The main theme of this research will concern the nature and distribution of the dark matter that makes up most of the mass of the universe. This will be explored in a variety of contexts, ranging from implications of particle physics theories of the origin of the universe to studies of the formation and evolution of galaxies and large scale structure in the Universe. An emphasis will be placed on developing predictions that can be tested by comparison with the rapidly increasing data. The ultimate goal of all this work is to contribute toward the creation of a fundamental theory of the origin, evolution, and matter content of the universe. Along the way, improved methods will be developed for working out the predictions of cosmological models and comparing them to observations, including state- of-the-art supercomputer simulation and visualization techniques. These techniques will be used for education and outreach as well, and will be made widely available so that other theorists and observers can use them.

研究将在宇宙学和理论基本粒子物理学方面进行。 这项研究的主题将涉及构成宇宙大部分质量的暗物质的性质和分布。 这将在各种背景下进行探索，从宇宙起源的粒子物理理论的含义到星系和宇宙大尺度结构的形成和演化的研究。 将重点放在开发可通过与快速增加的数据进行比较来测试的预测上。 所有这些工作的最终目标是为创建宇宙起源、演化和物质含量的基本理论做出贡献。 在此过程中，将开发改进的方法来制定宇宙学模型的预测并将其与观测结果进行比较，包括最先进的超级计算机模拟和可视化技术。 这些技术也将用于教育和推广，并将广泛提供，以便其他理论家和观察家可以使用它们。
