Abstract: We provide a classification of near-horizon geometries of supersymmetric,asymptotically anti-de Sitter, black holes of five-dimensional U1^3-gaugedsupergravity which admit two rotational symmetries. We find threepossibilities: a topologically spherical horizon, an S^1 \times S^2 horizon anda toroidal horizon. The near-horizon geometry of the topologically sphericalcase turns out to be that of the most general known supersymmetric,asymptotically anti-de Sitter, black hole of U1^3-gauged supergravity. Theother two cases have constant scalars and only exist in particular regions ofthis moduli space - in particular they do not exist within minimal gaugedsupergravity. We also find a solution corresponding to the near-horizongeometry of a three-charge supersymmetric black ring held in equilibrium by aconical singularity; when lifted to type IIB supergravity this solution can bemade regular, resulting in a discrete family of warped AdS3 geometries.Analogous results are presented in U1^n gauged supergravity.
