We construct new explicit solutions of general relativity from doubleanalytic continuations of Taub-NUT spacetimes. This generalizes previousstudies of 4-dimensional nutty bubbles. One 5-dimensional locallyasymptotically AdS solution in particular has a special conformal boundarystructure of $AdS_3\times S^1$. We compute its boundary stress tensor andrelate it to the properties of the dual field theory. Interestingly enough, wealso find consistent 6-dimensional bubble solutions that have only one timelikedirection. The existence of such spacetimes with non-trivial topology isclosely related to the existence of the Taub-NUT(-AdS) solutions with more thanone NUT charge. Finally, we begin an investigation of generating new solutionsfrom Taub-NUT spacetimes and nuttier bubbles. Using the so-called Hopf duality,we provide new explicit time-dependent backgrounds in six dimensions.Comment: 32 pages, 1 figure; v.3. typos corrected. Matches the published versio
