Abstract: We shall be investigating whether there is near-horizon supersymmetry enhancement in supersymmetric black hole solutions to minimal gauged supergravity in five dimensions; as all known black holes of the gauged theory exhibit supersymmetry enhancement from $1/4$ to $1/2$ in the near horizon limit, it is natural to investigate if this is generic. A further motivation is that one can demonstrate, assuming supersymmetry enhancement, the existence of two commuting rotational isometries of the full solution. It is known that under this latter condition there are no asymptotically AdS supersymmetric black ring solutions with regular horizons.
