Scientific paper

We propose to obtain a high spatial resolution temperature map of the core of the ``cooling flow'' cluster Abell 2029 to compare with detailed N-body+Hydro simulations on the same scale. Various pieces of evidence (no Halpha emission, no blue starlight, and the presence of a wide-angle-tail radio source) strongly suggest that the large central X-ray surface brightness excess is NOT due to a cooling with dot{M} > 100 M_{&sun;} yr(-1) but rather due to very hot shocked gas in a cluster-cluster merger. In this scenario filaments seen in the ROSAT HRI image are shock fronts which will remain unresolved with the ACIS-I, producing a spectacular AXAF image. The ACIS-I temperature will discern unambiguously if this cluster is a cooling flow or a merger event.
