Abstract:

We propsoe to observe the cluster of galaxies A3627, which has evidences of cluster merging, in order to detect hard X-rays from high energy particles acceralated in the cluster and also measure the doppler shift of the iron-K line. This cluster is a nearby bright cluster behind the Galactic plane, and thus so far X-ray studies have been poor. However, its proximity and relatively low temperature against other merging clusters enable us to constrain the hard X-ray emission more tightly.
