Kerr geodesics, the Penrose process and jet collimation by a black hole
Kerr geodesics, the Penrose process and jet collimation by a black hole
We re-examine the possibility that astrophysical jet collimation may arise from the geometry of rotating black holes and the presence of high-energy particles resulting from a Penrose process, without the help of magnetic fields. Our analysis uses the Weyl coordinates, which are revealed better adapted to the desired shape of …
