[2.17] Metal Enrichment in Abell 3571

R. A. Dupke, J. A. Irwin, J. N. Bregman (U. Michigan)

In this work we present Chandra and XMM spatially resolved spectroscopic analysis of the moderately rich (richness class 2) Bautz-Morgan Type I galaxy cluster Abell 3571 (z = 0.0397). Chandra observations allows us to study the core substructures of this cluster with unprecedented detail. The results are overall consistent with previous ASCA analysis but the metal abundance gradient becomes significantly steeper on very small scales (< 20"). We also find little evidence of cool gas in the core of the cluster. We discuss the results within the framework of current supernovae enrichment models.
