Scientific paper

It has been found with ASCA that both type II and Ia upernovae significantly contribute to metals in hot intracluster medium, based on the Si to Fe abundance ratio. In order to improve our understanding of relative contribution of both supernovae to the ICM, more accurate measurements of not only Fe but also other elemental abundances are necessary. However, such measurements is limited to rich clusters. Here we propose to observe a nearby bright poor cluster A3581 in order to measure abundance pattern of the overall ICM for O, Mg, Si, S, and Fe. Furthermore, we can study the ICM enrichment processes by deriving a large-scale abundance gradient of not only Fe but also Si for the first time.
