Outline of Final Research Achievements

We performed gamma-ray observations with Fermi gamma-ray telescope to gamma-ray bursts which is thought to have ultra-relativistic jet. High-energy gamma-rays observed by Fermi revealed that gamma-ray emission mechanism of gamma-ray bursts cannot be explained by standard scenario and we discussed motion of jet. In addition, we developed future instruments for observing gamma-ray bursts onboard Japanese next X-ray observatory ASTRO-H. We successfully fabricated flight model of sensors and performed on-ground calibrations as scheduled. Finally, we confirmed that instruments of ASTRO-H worked properly after launch.
