Abstract

The Weyl double copy relates exact solutions in general relativity to exact solutions in gauge theory, formulated in the spinorial language. To date, the Weyl double copy is understood and employed only for vacuum spacetimes, and hence only to vacuum gauge theories. In this Letter, we propose an extension to the Weyl double copy that provides a systematic procedure for treating gravitational sources. We show that this extended Weyl double copy gives a new perspective to the Kerr-Newman black hole and the general class of Petrov type D electrovac spacetimes.
