9318617 Sellwood Current understanding of the structure, origin and evolution of galaxies has advanced enormously in the last decade, due in part to advances in astronomical detector technology, and in part to advances in computer power and theoretical insight. The grant will address a number of closely related fundamental questions in galactic dynamics, including: the origin and evolution of disk and spheroidal galaxies, with particular focus on the role of dynamical instabilities; the structure of triaxial elliptical galaxies, especially those with large centric densities; and the dark matter content of a wide class of stellar systems, including elliptical and barred galaxies. Included in the research are: analysis of large-scale N-body simulations; analytical and semi-analytical studies; and analysis of observational data. ***

小行星9318617 在过去的十年里，对星系结构、起源和演化的理解有了巨大的进步，部分原因是天文探测器技术的进步，部分原因是计算机能力和理论洞察力的进步。 该赠款将解决银河系动力学中一些密切相关的基本问题，包括：盘状和球状星系的起源和演化，特别关注动力学不稳定性的作用;三轴椭圆星系的结构，特别是那些具有大中心密度的星系;以及包括椭圆星系和棒星系在内的各种恒星系统的暗物质含量。 研究包括：大规模N体模拟分析;分析和半分析研究;以及观测数据分析。 ***
