​The Latte Project is a new suite of cosmological zoom-in baryonic simulations that model the formation of Milky Way-like galaxies at parsec-scale resolution, using the FIRE (Feedback in Realistic Environments) model for star formation and stellar feedback. Using these simulations, I examine the roles of accretion and stellar feedback in driving the formation and structure of disk galaxies like the Milky Way. The Latte simulations also self-consistently resolve the dwarf galaxies that form around each host, and I will discuss the relative impacts of internal stellar feedback and external environment on their star formation histories, stellar kinematics, and chemical enrichment histories, including progress in addressing the long-standing “missing satellites” and “too-big-to-fail” problems of LCDM cosmology. Finally, I discuss promising new avenues for using upcoming observations to test the role of feedback in dwarf galaxies.
