| Outline of Final Research Achievements |
The particle acceleration and succeeding X/gamma-ray emission mechanisms in high-energy astronomical objects have not been revealed yet. In order to establish a new picture beyond the previous simple models, we develop numerical simulation codes that can follow the temporal evolutions of particle acceleration, injection, and emissions. We propose a slow acceleration process due to turbulence rather than shock wave, which has been mostly considered as the acceleration site. Our models succeed in reproducing the emissions from jets launched from active galactic nuclei, and gamma-ray bursts, and so on. Our results propose a new picture for high-energy astrophysical objects. For the turbulence acceleration, the time-dependence is essential to reproduce the observations, so that our unique method is a powerful tool to investigate the particle acceleration and emissions.
