Electrically charged black holes and the Blandford–Znajek mechanism
Electrically charged black holes and the Blandford–Znajek mechanism
Recently, it was claimed that accretion of electric charge by a black hole rotating in an aligned external magnetic field results in a "dead" vacuum magnetosphere, where the electric field is totally screened, no vacuum breakdown is possible, and the Blandford-Znajek mechanism cannot operate King & Pringle (2021). Here we …
