A class of , with
being a two-sphere or a hyperbolic space, solutions within four-dimensional
gauged supergravity coupled to three-vector multiplets with dyonic gauging is identified. The gauged supergravity has a non-semisimple
gauge group and can be obtained from a consistent truncation of 11-dimensional supergravity on a tri-sasakian manifold. The maximally symmetric vacua contain
geometries with
supersymmetry corresponding to
and
superconformal field theories (SCFTs) in three dimensions. We find supersymmetric solutions of the form
preserving two supercharges. These solutions describe twisted compactifications of the dual
and
SCFTs and should arise as near horizon geometries of dyonic black holes in asymptotically
space-time. Most solutions have hyperbolic horizons although some of them exhibit spherical horizons. These provide a new class of
geometries with known M-theory origin.
