| Outline of Final Research Achievements |
Gamma-Ray Bursts (GRBs) and Active Galactic Nuclei (AGNs) are the two archetypical phenomena among astrophysical jets. This study consists of multi-wavelength observational study of these objects to investigate (A) the life of the jets, (B) physics of radiation region, and (C) circumstances including intergalactic warm-hot plasma. Through this study we realized that: the life time of AGN jets is up to 100 Myears with a fairly constant energy ejection; the radiation of the GRB prompt emission consists both of non-thermal synchrotron and thermal blackbody like emissions. We also developed X-ray micro-calorimeter system for the next generation X-ray observatory ASTRO-H and made observation plan to reveal warm-hot intergalactic medium irradiated by GRB or relativistically beamed AGN jets.
