Title: DECam Magellanic Clouds Survey Pilot Program

Abstract: As two of our closest galactic neighbors, the Magellanic Clouds (MCs) have long been enticing targets for investigating galaxy formation and evolution, especially of interacting systems. The commissioning of the wide-field Dark Energy Camera (DECam) on the CTIO-4m will enable the next generation of large-scale and deep photometric surveys of the Magellanic Clouds. We aim to propose for a community DECam survey of the Clouds covering hundreds of deg^2 to ~25th mag in multiple filters that will complement the Dark Energy Survey's partial coverage of the Magellanic periphery. Such a survey would make possible a number of important scientific inquiries: (1) Mapping the stellar periphery of the MCs with old main-sequence turnoff stars that should reveal relics of their formation and past interactions. (2) Spatially-resolved star formation histories covering all ages of the MCs that will further complement our understanding of their past evolution. (3) 3D mapping of the complex geometries of the MCs with RR Lyrae variable stars. And, finally, (4) use the large-scale stellar and \ionH1 distributions to probe the nature of the hot gaseous Galactic halo. We propose here a pilot program using shared risk time to study and evaluate the best observing and data strategy for a future DECam Magellanic Clouds survey.
