Outline of Final Research Achievements |
This research aims to study the overall structure of the high-energy phenomena in the central region of our galaxy. During this research, we found high energy phenomenon in the region: a huge plasma of 100 million K extending over the Galactic center region, and X-ray reflection nebulae, i.e. X-ray emitting molecular clouds, which are evidence for past high activity of the super massive black hole, Sagittarius A*. Unfortunately, launch of the next X-ray observatory, ASTRO-H, was postponed, and hence this research did not reach the goal. After ASTRO-H will be launched in FY2015, we will reveal the relationship among those high-energy phenomena in the Galactic center region.
