Near-horizon structure of escape zones of electrically charged particles around weakly magnetized rotating black hole. II. Acceleration and escape in the oblique magnetosphere

Understand

Strong gravity and magnetic fields are key ingredients that power processes of accretion and ejection near compact objects.

• While the particular mechanisms that operate here are still discussed, it seems that the presence of an ordered magnetic field is crucial for the acceleration and collimation of relativistic jets of electrically charged particles on superhorizon length scales.
• In this context, we further study the effect of a large-scale magnetic field on the dynamics of charged particles near a rotating black hole.
• We consider a scenario in which the initially neutral particles on regular geodesic orbits in the equatorial plane are destabilized by a charging process (e.g., by photoionization).
