Abstract:

We propose to observe the north-west region in nearby merging cluster Abell 3627. Suzaku observation in AO-3 found a subcluster colliding into the main body from the south-east direction and a hard X-ray component above 12 keV probably originated from the north-west region. The region has also peculiar structures such as long X-ray/radio tails, suggesting a relation with the cluster merging. In order to understand the process of cluster merging taking into accout the hard X-ray component and these peculiar structures, we will measure the temperature and pressure distributions in the north-west region using the low background of XIS. We will also study the non-thermal emission using HXD and investigate a possibililty of the particle acceleration in Abell 3627.
