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中进行。 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。 这将在各种环境中进行探讨，从宇宙起源的粒子物理理论的含义到对星系的形成和演变的研究以及宇宙中的大规模结构。 将重点放在开发预测，可以通过与迅速增加的数据进行比较来测试。 所有这些工作的最终目标是为创建宇宙，进化和物质内容的基本理论做出贡献。 一路上，将开发改进的方法来确定宇宙学模型的预测，并将其与观察结果进行比较，包括现状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宣传，并将广泛使用，以便其他理论家和观察者可以使用它们。
