摘要：

It is observed that three-dimensional Godel black holes can be promoted to exact string theory backgrounds through an orbifold of a hyperbolic asymmetric marginal deformation of the SL(2,R) Wess-Zumino-Witten model. Tachyons are found in the spectrum of long strings. Uplifting these solutions in type IIB supergravity, extremal black holes are shown to preserve one supersymmetry in accordance with the Banados-Teitelboim-Zanelli limit. We also make connections with some recently discussed warped black hole solutions of topologically massive gravity.
