9402455 Primack Theoretical research in cosmology and particle physics will focus on the nature and distribution of the dark matter (DM) in the universe. A major part of the research will involve construction and analysis of models, currently concentrating on Cold + Hot Dark Matter (CHDM), and detailed comparison with observational data. A closely related major subject of the research will be the spatial distribution of dark matter in the universe as revealed both via large-scale velocity flows and the velocity curves of spiral galaxies. There will also be study of the origin of the density fluctuations during inflation and the implications for large scale clustering and the cosmic microwave background. The research to be undertaken deals with centrally important questions about what the universe is, and how it came to be. ***

9402455 Primack宇宙学和粒子物理学的理论研究将集中在宇宙中暗物质（DM）的性质和分布上。研究的一个主要部分将涉及模型的构建和分析，目前主要集中在冷+热暗物质（CHDM），以及与观测数据的详细比较。一个密切相关的主要研究课题将是暗物质在宇宙中的空间分布，这是通过大尺度速度流和螺旋星系的速度曲线所揭示的。还将研究膨胀期间密度波动的起源以及对大规模群集和宇宙微波背景的影响。即将进行的研究涉及的是关于宇宙是什么以及它是如何形成的核心重要问题。＊＊＊
