Numerical Studies of Rich Clusters

布雷纳德博士将使用高分辨率数值模拟研究丰富星系团的形成。嵌套的网格代码将用于跟踪富集群的演变。将确定流行的分级模型中最丰富的星系团的全部历史，并将这些星系团的物理属性与现有的观测结果进行比较，以评估模型重现观察到的星系团的可行性。这些数字星系团将构成一个高分辨率测试星系团的数据库，用于研究诸如引力透镜等对一组遥远源星系的影响。

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.
