3C324 comma the cluster of galaxias with a type-2 QSO

3C324 is a powerful radio galaxy at z1.2 and the surrounding galaxy cluster has been extensively studied. In particular, Xray emission detected with ASCA has a hard spectrum described by a superposition of thermal cluster emission and heavily absorbed AGN powerlaw emission. This is very suggestive of the existence of a type2 QSO. We propose the 30 ksec XMM observation of 3C324 in order to separate the cluster and the QSO emission. The Iron abundance and the temperature of intracluster gas will constrain the evolution of metallicity and the formation history of clusters in the highz universe, respectively. Furthermore, measuring the absorption column density of the obscured quasar is important in relation to the composition of the Cosmic Xray Background. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
