Outer Spiral Disks as Clues to Galaxy Formation and Evolution
Abstract
Recent studies of outer spiral disks have given rise to an abundance of new results. We discuss the observational and theoretical advances that have spurred the interest in disk outskirts, as well as where we currently stand in terms of our understanding of outer disk structure, ages, and metallicities.
