Abstract: We present hydrodynamical simulations in a ΛCDM framework with resolution sufficient to resolve the inhomogeneous structure of the interstellar medium. Feedback from star formation is then able to unbind gas, creating strong gas outflows. These simulations form analogues of present day dwarf galaxies (Vpeak < 60 km s-1) that are simultaneously “bulgeless” and have a cored DM distribution, demonstrating for the first time that the formation of a central dense stellar and DM component is not inevitable in hierarchical models, and reconciling observations of dwarf galaxies with the CDM model.
