| Outline of Final Research Achievements |
In curved spacetime such as black hole spacetime, there is no numerical method to accurately solve general relativistic (GR) photon Boltzmann equation (radiative transfer equation) for arbitrary optical thickness of photon. In this study, we proposed a new method to solve GR photon Boltzmann equation with photon processes of emission, absorption and scattering, and developed a new GR radiative transfer equation solver, ARTIST (Takahashi, Umemura, 2017, MNRAS, 464, 4567). By ARTIST code, we can perform GR radiative transfer simulations which correctly reproduce results of GR ray-tracing calculations with high accuracy.
