Scientific paper

The GHOSTS survey is the largest study of the resolved stellar populations in the outskirts of disk galaxies to date. Using the GHOSTS sample of 14 nearby galaxies, this presentation will explore the phenomenon of disk truncations and show how the data support the idea of substantial stellar migration in the galaxy disk and beyond. Such migrations may have important ramifications for the study of disk-galaxy evolution. Future directions for this work, and the GHOSTS survey as a whole, will also be discussed.
