| Research Abstract |
I have studied the mechanism of 'ultra-high-energy radiation' originated near a black hole (BH). I have also discussed a model of BH engine as the source of activity for their astronomical objects in the framework of general relativistic magneto-hydro dynamics (GRMHD). In this research, specially, I have made clear the conditions for the GRMHD accretion onto a BH, and the conditions for the GRMHD shock in accretion. I showed a very interesting result that the extracted energy of the rotating BH by electromagnetic process can convert to the thermal energy at the shock front.
