We derive the matching conditions between FLRW and generalised Vaidyaspacetimes with spherical, planar or hyperbolic symmetry, across timelikehypersurfaces. We then construct new models of gravitational collapse of FLRWspacetimes with a negative cosmological constant having electromagneticradiation in the exterior. The final state of the collapse are asymptoticallyAdS black holes with spherical, toroidal or higher genus topologies. We analysethe collapse dynamics including trapped surface formation, for variousexamples.
