Outline of Final Research Achievements

We have developed a new X-ray radiation calculation code based on Monte Carlo methods toward new/next generation high-precision observations of cosmic X-rays. This code called MONACO is a multi-purpose framework applicable to a variety of astrophysical objects. MONACO treats physical processes of inverse Compton scattering in a hot accretion flow, a photo-ionized plasma, and X-ray reflection from cold matter. We have applied these astrophysical models to accretion flows onto neutron stars and black holes, ultra fast outflows from active galactic nuclei, dusty tori in active galaxies, and accretion disk coronae around white dwarfs, and established data analysis system based on precise Monte-Carlo models for X-ray observatories such as Suzaku, Chandra, and XMM-Newton.
