A global view on Kerr spacetime -- visualizing the maximal analytic extension — •Thomas Reiber — Universität Hildesheim

The maximal analytic extension of slow Kerr spacetime contains an infinity of asymptotically flat "exterior" regions connected by a strongly curved region. An observer may stay in one of the exterior regions or - crossing event horizons - pass through the strongly curved region to reach one of the other asymptotically flat regions. We calculate videos of what such an observer would see by using general relativistic ray tracing in the maximal analytic extension of Kerr spacetime. For that purpose we use a covering af Kerr spacetime by a atlas consisting of Kerr-Schild and Kruskal-like coordinate patches.
