| Research Abstract |
Adopting either (1)Gamma Ray Bursts (GRB) as a distance indicator, (2)Progenitor and host galaxy of GRB, (3) Supernova associated with GRB, (4)Emergence and propagation of jets, or (5)Radiation mechanism of prompt emission and afterglow of GRB etc as a research theme of each member, we performed the cooperative research program on GRB using TV conference system to communicate each other frequently. As a result, we succeeded in (1)simulating the formation of the first stars without metal and evolving them up to be seen as GRBs. (2)We also reanalyzed Yonetoku relation as a distance indicator to the first GRB and found that Yonetoku relation is a good distance indicator if we restrict only data within 10% errors and define the luminosity in the rest frame of GRBs. Besides these researches , big progress in (3)the origin of Yonetoku relation (4)the origin of the shallow decay phase of GRBs (5) relativistic MHD numerical simulations to clarify the origin of energy of GRBs etc. has been made.
