Smooth time dependent supergravity solutions corresponding to analyticcontinuations of Kerr black holes are constructed and limits with a local deSitter phase are found. These solutions are non-singular due to a helical twistin space and a fine tuning of the energy flow in the spacetime. For theextremal limit in which the mass and twist parameters are equal the S-braneundergoes de Sitter expansion. Subextremal limits show the formation and decayof a twisted circle and closed string tachyon condensation backreaction effectscan be followed. For small values of the twist deformation, a short livedergosphere envelopes the S-brane and leads to the production of closed timelikecurves.Comment: 26 pages, 8 figures. v2 references added, typos correcte
