Session 95 - X-Ray Galaxies and Clusters.
Oral session, Wednesday, January 17
La Condesa, Hilton
We examine the creation and evolution of X-ray clusters in a few different cosmologies using a new adaptive-mesh refinement (AMR) hydrodynamics algorithm. This Eulerian method places uniform grids of finer resolution over areas of interest in order to obtain high resolution in the centers of clusters while keeping shocks reasonably well resolved in low density areas. The algorithm is based on extensions to that originally described by Berger and Colella (1989). This process can give resolution of tens of kpc (in selected regions) in a box 50 Mpc on a side. Cluster structure and evolution will be discussed.
