Title: Magellanic Satellites Survey: The Search for Hierarchical Structures within the Local Group (Phase 2)

Abstract: The standard cosmological model with cold dark matter generically predicts a hierarchy of structure on mass scales ranging from galaxy clusters to ultra-faint galaxies. The Magellanic Satellites Survey (MagLiteS) is specifically designed to test this paradigm, on the smallest scales explored to date, through a systematic search for galaxies associated with the Large and Small Magellanic Clouds. We have discovered several ultra-faint galaxy candidates with DECam imaging during the first phase of MagLiteS. At least two of these have measured line-of-sight systemic velocities consistent with the orbits of Magellanic satellites predicted by numerical simulations. To rigorously examine the apparent clustering of satellites around the Magellanic system, we propose a continuation of the MagLiteS program to cover an additional $sim1300$~deg$^2$ of unexplored sky near the Clouds. In combination with Pan-STARRS and other DECam surveys, MagLiteS will help to complete a deep ($sim23$~mag) multi-band ($gr$) survey of the entire high-Galactic-latitude sky ($|b| > 10$~deg), providing a definitive legacy dataset for population studies of substructure in the Milky Way halo.
