Abstract

We explicitly establish that the Kerr metric represents a pair of self-dual and anti-self-dual gravitational dyons (Taub-NUT instantons). We show that the Newman-Janis algorithm precisely originates from this fact. More generally, this program of understanding four-dimensional black holes as systems of chiral dyons extends to Kerr-Newman and Kerr-Taub-NUT solutions as well.
