A bstract We use the recipe of [1] to find half-BPS near-horizon geometries in the t 3 model of N = 2, D = 4 gauged supergravity, and explicitely construct some new examples. Among these are black holes with noncompact horizons, but also with spherical horizons that have conical singularities (spikes) at one of the two poles. A particular family of them is extended to the full black hole geometry. Applying a double-Wick rotation to the near-horizon region, we obtain solutions with NUT charge that asymptote to curved domain walls with AdS 3 world volume. These new solutions may provide interesting testgrounds to address fundamental questions related to quantum gravity and holography.
