Scientific paper

Clusters of galaxies are excellent laboratories for the study of the nucleosynthesis and chemical enrichment history of the Universe. These studies are currently biased toward relatively cooler (2-4 keV) clusters. However, the enrichment history of the massive hot clusters might be different from that of the smaller and cooler systems. Therefore, we propose to enlarge the sample of clusters observed with the RGS on XMM-Newton with Abell 2029, a hot luminous massive cluster with a cooling core. Despite of the high mass of this system, the cool gas in the core will allow us to measure the abundances of many elements. A deep (130 ks) observation will provide us with EPIC and RGS spectra of excellent statistics, which allows us to accurately measure the abundances O, Ne, Mg, Si, S, Ar, Ca, Fe, and Ni.
