Brainerd, Tereasa AST 96-16968 Dr. Brainerd will investigate the formation of rich clusters of galaxies using high resolution numerical simulations. A nested grid code will be used to follow the evolution of rich clusters. The infall history of the richest clusters in popular hierarchical models will be determined and the physical properties of the clusters will be compared to available observational results to assess the viability of the models to reproduce observed clusters. The numerical clusters will constitute a database of high resolution test clusters for investigating effects such as gravitational lenses for a population of distant source galaxies.

Brainerd，Tereasa AST 96-16968 Brainerd博士将使用高分辨率的数值模拟研究富的星系簇的形成。 嵌套网格代码将用于遵循丰富的簇的演变。 将确定流行层次模型中最富有的群集的插入历史，并将簇的物理性质与可用的观察结果进行比较，以评估模型的生存能力，以重现观察到的簇。 数值簇将构成一个高分辨率测试簇的数据库，用于研究诸如远处源星系群的重力镜片之类的效果。
