Research Abstract

Compton-thick active galactic nucleus (AGN) are objects whose nucleus are heavily obscured by thick matter (N_H>10^24 cm^<-2)>, and are key objects to study the evolution of AGN. We have explored the characteristics of bright Compton-thick AGNs such as nuclear activity and obscuring column with X-ray satellites, Suzaku and so on. A large X-ray observatory is crucial to reveal the nature of AGNs. We have developed elemental technologies for production of a large X-ray telescope.
