Charging of rotating black holes: kinetic simulations of black hole magnetospheres

Martin Kološ, Farukh Abdulkhamidov, Arman Tursunov +2

Whether a rotating black hole (BH) immersed in an external magnetic field charges up to the Wald value $Q_{\mathrm{W}}=2aMB$, where $M$ and $a$ are the BH mass and spin parameter, and $…
