General Relativistic Simulations of Jet Formation in Kerr Black Hole Magnetosphere

Abstract_

It is believed that relativistic jets from several kinds of objects in the universe are all formed by violent phenomena near the black holes. Among the proposed mechanisms, the magnetic mechanism of the jet formation becomes most promising because it may explain not only the acceleration but also the collimation of the jets. However, the distinct mechanism has not yet been shown. Here we report a numerical result of jet formation driven by magnetic field due to the current loop near a rapidly rotating black hole. In such magnetic configuration, there are magnetic flux tubes which bridge the region between the ergosphere and the disk around the black hole. The result clearly shows that the `magnetic bridge' between the ergosphere and the disk is not stationary and expands explosively to form a relativistic jet.
