| Research Abstract |
We have developed numerical simulation codes of general relativistic accretion flow and radiative transfer in order to perform theoretical calculations which are required to interpret observational data of black hole obtained by telescopes in near future. Based on these codes, we calculated accretion flows around rotating black holes and performed radiative transfer calculations. Then, observational signatures in radio band and X-ray were calculated and their observational feasibilities are investigated. Moreover, these calculation codes are developed to be used for the cases of other gravity theories than the general relativity.
