General relativistic effects of plasma accreting into black holes in the centers of nearby galaxies

我们开发了广义相对论吸积流和辐射传输的数值模拟程序，以便进行理论计算，以解释不久的将来由望远镜获得的黑洞观测数据。基于这些程序，我们计算了旋转黑洞周围的吸积流，并进行了辐射传输计算。然后，计算了射电波段和X射线的观测特征，并研究了它们的观测可行性。此外，这些计算程序还可用于广义相对论以外的其他引力理论的情况。

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.
