摘要：

1 present a model of high-energy emission sources generated by a standing magnetohydrodynamical (MHD) shock in a black hole magnetosphere. The black hole magnetosphere would be constructed around a black hole and an equatorial accretion disk, and can be considered as a model for a central engine of active galactic nuclei (AGNs) and gamma-ray bursts (GRBs). From the analysis of MHD shock conditions for accreting plasma onto a black hole, we obtain the restrictions on the flow's physical parameters, and examine the distribution of the shock front. Then, we find that an off-equatorial Aurora-like shaped hot plasma region is possible by the MHD shock formation when the magnetosphere rapidly rotates; the hot plasma region locates close to the event horizon. The emission from this off-equatorial sources would carry new information about the strong gravitational field to us.
