Research in cosmology and particle physics will focuson the nature and distribution of dark matter in the universe. Using very high resolution simulations and other methods, the project will investigate all the issues that have been raised concerning the hypothesis that cold dark matter (CDM) makes up most of the dark matter in the halos of galaxies. If any of these issues actually turn out to be serious problems, it may mean that the main component of dark matter in galaxy halos and on larger scales is not CDM, and it may give us clues regarding the properties of the dark matter. The project will also study the implications of the simulations and data for dark matter detection via the detection of the mutual annihilation of particles that make up the dark matter. The research will also study the constraints on cosmological parameters, including neutrino mass, from cosmological structure formation, in particular the formation of far away galaxies. This work is very important, since it will clarify the nature of most of the matter in the universe.

宇宙学和粒子物理学的研究将集中于宇宙中暗物质的性质和分布。 该项目将使用非常高分辨率的模拟和其他方法，研究有关冷暗物质（CDM）构成星系晕中大部分暗物质这一假设的所有问题。 如果这些问题中的任何一个实际上成为严重问题，则可能意味着星系晕和更大尺度上的暗物质的主要成分不是CDM，并且它可能为我们提供有关暗物质性质的线索。 该项目还将通过检测构成暗物质的粒子的相互湮灭来研究模拟和数据对暗物质检测的影响。 该研究还将研究宇宙学结构形成，特别是遥远星系的形成对宇宙学参数（包括中微子质量）的限制。 这项工作非常重要，因为它将阐明宇宙中大多数物质的本质。
