Abstract:

To investigate hot gas properties of a large scale filament, we propose Suzaku observation (92 ks) of a filamentary structure between Abell 3391 and Abell 3395. A3391 and A3395 are located in Horologium supercluster and expected to be in an initial phase of a cluster merger. With Suzaku fs high sensitivity observation, we will (i) determine the physical conditions of IntraCluster Medium by measuring the temperature and density distribution, (ii) unveil the origin of the filamentary structure from distribution of abundance, pressure and entropy. Our study will reveal the formation history of the filament and provide a useful information for the future Sunyaev-Zeldovich effect observations.
