Black Holes and Magnetic Field
- Romana Mikusincova (Universita degli Studi Roma Tre)
Large scale magnetic fields pervade the cosmic environment and the astrophysical black holes are often embedded and influenced by the mutual interaction. We will outline the appropriate mathematical framework to describe magnetized black holes within General Relativity and we will show several examples how these can be employed in the astrophysical context.
The study of charged test particle dynamic in the combined black hole gravitational field and magnetic field around it could provide important theoretical insight into astrophysical processes around such compact objects. We will examine simple but astrophysically relevant parabolic magnetic field configuration as a toy model for magnetosphere around Schwarzschild black hole. Bounded orbits and...
We study charged non-conducting fluid tori orbiting in the background given by a Schwarzschild
black hole immersed in a parabolic magnetic field introduced in the context of the Blandford–Znajek
process. In our study we focus on the off-equatorial charged tori that could be related to creation
of jets due to the Blandford-Znajek process.
