Revisiting the dyonic Majumdar{Papapetrou black holes

Abstract

We extend the Majumdar{Papapetrou solution of the Einstein{Maxwell equations, which are implied generallyfor static electric charge in nonrotating metrics, to encompass equally well magnetic charges. In the absence of Higgs andnon-Abelian gauge elds, 'dyonic' is to be understood in this simpler sense. Cosmologically this may have far-reachingconsequences, to the extent that existence of multimagnetic monopole black holes may become a reality in our universe.Infalling charged particle geodesics may reveal, through particular integrals, their inner secrets, which are screened fromour observation.
