Abstract

Relativistic jet phenomena are most often observed in the vicinity of the black holes which are undergone by the surrounding plasma accretion. The crucial role of the magnetic field is generally accepted, and reveals itself in the form of influence on the accretive plasma behaviour. Primarily, the magnetic field links the central source with an ambient plasma and can be considered as a set of the wires which transport the energy over the black hole and back, by means of the magnetohydrodynamical (MHD) waves.

Moreover, magnetic field is able to plasma flow collimation that can give a rise to relativistic jet creation. To investigate a magnetized plasma accretion onto a spinning black hole we performed a number of numerical calculations. Our results clearly demonstrated that such interaction leads to the process of the energy extraction from the rotation black hole, which is attended with the relativistic jet creation. Implication of reconnection process in our calculation gives rise to the plasmoid origin, which moving outward from the black hole carries away the energy and angular momentum. The described process can be repeated over and over, eventually the jet structure is composed of a chain of plasmoids which are propagated along the spin hole axis.
