| Outline of Final Research Achievements |
We have studied the acceleration mechanisms of high energy particles in various galactic objects such as supernova remnants, microquasars, pulser winds, by combining very-high-energy (VHE) gamma-ray observations with the atmospheric Cherenkov telescope H.E.S.S., gamma-ray observations by the Fermi satellite, and X-ray observations. We focused on observations of the supernova remnant RXJ 1713.7-3946 which is one of the strongest gamma-ray sources on the VHE gamma-ray sky, and discovered gamma rays extending beyond the X-ray shell. Also we have measured the expansion rate of the remnant, and performed the first hard X-ray imaging using NuSTAR.
