| Outline of Final Research Achievements |
Galaxy clusters are the largest object in the universe. High mass density and clumpy structure, namely subhalos, exist in galaxy clusters. The subhalo masses can be measured by weak-gravitational lensing analysis, and physical properties for hot gas in clusters are by X-ray observations. Our studies based on this funding reveals the following main results. 1) X-ray follow-up observation discovered hot gas associated with subhalos previously discovered by weak-lensing analysis and found a stripping feature. 2) Mass profile for dark subhalo associated with a giant, central elliptical galaxy and the entire region are measured by joint weak-lensing and stellar kinematics analysis. 3) Giant synchrotron radio emission traces the projected mass distribution for one merging cluster.
