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数值模拟研究丰富的星系团的形成。 将使用嵌套网格代码来跟踪丰富集群的演变。 将确定流行分层模型中最丰富簇的流入历史，并将簇的物理特性与可用的观测结果进行比较，以评估模型重现观察到的簇的可行性。 这些数值星团将构成一个高分辨率测试星团的数据库，用于研究诸如引力透镜对遥远源星系群的影响。
