Outline of Final Research Achievements

We developed the X-ray astronomical satellite, ASTRO-H, and applied a new analysis method utilizing Monte-Carlo simulations to the data which already observed with current instruments, for the purpose of revealing physical properties of the ultra-fast outflows (UFOs), which are thought to play an important role in the coevolution of galaxies and black holes.
Unfortunately, we were not able to realize high-sensitivity observations of UFOs with ASTRO-H due to the mishap occurred 1 month after the launch. But we successfully confirmed good performances of the hard X-ray imager which we had been developed. These results would be very important and useful for future high-sensitivity missions. On the other hand, by the analyses with the new method, we obtained results which could have impacts on spin measurements of black holes and studies on acceleration mechanisms of the UFOs.
