Near Horizon Geometry of Rotating Black Holes in Five Dimensions
Abstract
We interpret the general rotating black holes in five dimensions as rotating black strings in six dimensions. In the near horizon limit the geometry is locally AdS3 x S3, as in the nonrotating case. However, the global structure couples the AdS3 and the S3, giving angular velocity to the S3. The asymptotic geometry is exploited to count the microstates and recover the precise value of the Bekenstein- Hawking entropy, with rotation taken properly into account. We discuss the perturbation spectrum of the rotating black hole, and its relation to the underlying conformal field theory.
