Scientific paper

Abundance studies of clusters of galaxies are giving us important clues about the chemical enrichment history of the universe. These studies are currently biased toward cool and cooling core clusters. However, the enrichment history of the non-cooling core and massive hot clusters is different. Therefore, we propose to observe two very different clusters: A 2029 and A 1775, each for 130 ks. While A 1775 is a medium mass, non-cooling core cluster with a low density, A 2029 is a hot massive cluster with a cooling core. The excellent statistics of the EPIC and RGS spectra will allow us to accurately measure the abundances of many elements. Comparison of these two clusters will allow us to study the variation of the star formation and enrichment processes with large scale environment.
