Twistor quadrics and black holes

Published 20 Dec 2022 in gr-qc and hep-th | (2212.10491v1)

Abstract: A simple procedure is given to construct curved, non-self-dual (complexified) Kaehler metrics on space-time in terms of deformations of holomorphic quadric surfaces in flat twistor space. Imposing Lorentzian reality conditions, the Schwarzschild, Kerr, and Plebanski-Demianski space-times (among others) are derived as examples of the construction.
