| Outline of Final Research Achievements |
The birth and growth of a super massive black hole (SMBH) at the center of the galaxy has become one of the most important issues in astrophysics. The active galaxy nucleus (AGN) we focused on is a hidden AGN in a large amount of material, which is a key object to clarify SMBH evolution. We used a broad band X-ray spectrum, including the hard X-ray band above 10 keV, and revealed hidden AGN activity and surrounding material structures. The number of hidden AGNs detected is less than the prediction, and there may be more undetected AGNs. We studied a new method to find out the hidden AGNs in X-ray source catalogues. Direct verification of evolutionary scenarios of SMBH is to observe growing black holes. We have developed a carbon-fiber-reinforced plastic mirror with a monolithic Wolter type I geometry. The development of our elemental technology leads to the large-area high-angle resolution X-ray telescope required for this direct verification.
