Outline of Final Research Achievements |
In order to unravel radiation mechanisms of gamma-ray bursts (GRBs) which is one of the biggest explosion in the Universe, we carried out wide-band observations from X-rays to GeV gamma-rays focusing on X-rayu range below 10 keV with MAXI and CALET Gamma-ray Burst Monitor (CGBM) on the International Space Station (ISS) which was successfully launched in August 2015. The CGBM observed 61 GRBs so far (4 GRBs were simultaneously detected by MAXI), and searched for X-ray and gamma-ray counterpart of gravitational wave e\vents. MAXI observed 64 GRB candidates, and more than half of them are classifed to X-ray flashes (XRFs) whose radiations are dominant in X-rays. Furhtermore, we found that there were some weak events with soft X-ray spectrum and no X-ray conterparts found in the Swift follow-up observation. These events might be a new class for transient sources.
