Charged particles and Penrose process near charged black holes in Einstein–Maxwell-scalar theory
Abstract We study the dynamics of charged test particles around an electrically charged black hole in Einstein–Maxwell-scalar (EMS) gravity. The event horizon properties of the spacetime around the black hole are explored and the upper limit for the EMS theory parameters corresponding to extreme cha...
