Title: Imaging of Dwarf Galaxy Candidates

Abstract: Dwarf galaxies are important to theories of galaxy formation, the distribution and nature of dark matter, the processes of star formation, and the origin and growth of large-scale structure. Extremely low- luminosity dwarfs are only detectable at very short distances, within or near the Local Group, so very few are known. The first part (southern hemisphere) of an all-sky survey to discover more has resulted in two new Local Group dwarfs as well as several nearby dwarfs, and has placed strict limits on the number yet undiscovered there. Extending our survey to the northern sky, we have found several more nearby dwarfs and refined the limits on the Local Group luminosity function. We propose to continue followup imaging of our candidate objects. We note that ours is the only deep, all-sky survey of its type.
