Query: Merging Binary Clusters   We study three prominent bi-modal X-ray clusters: A3528, A1750 and A3395.
Using observations taken with ROSAT and ASCA, we analyze the temperature and
surface brightness distributions. We also analyze the velocity distributions of
the three clusters using new measurements supplemented with previously
published data. We examine both the overall cluster properties, as well as the
two sub-cluster elements in each. These results are then applied to the
determination of the overall cluster masses, and demonstrate excellent
consistency between the various methods used. While the characteristic
parameters of the sub-clusters are typical of isolated objects, our temperature
results for the regions between the two sub-clusters clearly confirm the
presence of merger activity. These three clusters represent a progression of
equal-sized sub-cluster mergers, starting from initial contact to immediately
before first core passage.
