| Research Abstract |
The goals of this research are quick and precise localization of gamma-ray bursts (GRBs) which lead to prompt observations of afterglows, and investigation of origins and environments of GRBs from detailed X-ray and gamma-ray studies. We developed MAXI and succeeded in detecting and reporting GRBs. We also conducted basic development of X-ray spectrometers and GRB localization instruments. In addition, we analyzed the data obtained by satellites as HETE-2, Fermi, and Suzaku, and studied the correlation between the peak spectral energy and the luminosity, and the energy dependence of the X-ray/gamma-ray light curves.
