Keys to Cosmology - Clusters of Galaxies
arXiv:astro-ph/0309172 · doi:10.1088/1009-9271/3/S1/97
Abstract
We review several aspects of clusters of galaxies and their application to cosmology. We present first results of numerical simulations of the dynamics of the intra-cluster gas and of different interaction processes between cluster galaxies and the intra-cluster gas. In particular metallicity maps are very useful to determine the importance of the different interaction processes. Also mass determination methods and possible sources for uncertainties in the measurements are shown.
