A simple hyperboloidal foliation of Kerr-Newman spacetime

Abstract

Hyperboloidal foliations which extend to future null infinity are advantageous in extracting gravitation radiation and monitoring the approach to horizon formation. A simple hyperboloidal foliation of the Kerr-Newman family of charged, spinning black hole spacetimes is presented. Its potential application to the simulation of the full range of perturbations of sub-extremal Kerr-Newman black holes is outlined.
