The Galactic Center Workshop 2009 will be devoted to the presentation and discussion of recent observational and theoretical results on low-luminosity galactic nuclei. In particular, the center of the Milky Way will be emphasized to give a close-up view of such a nucleus, resolving structures from scales of hundreds of parsecs down to a few milliparsecs, and thus to explore the implications for our understanding of other galactic nuclei. Developments in the study of low-luminosity galactic nuclei in nearby galaxies will also be highlighted to provide complementary perspectives -- global and relatively unobscured -- which are particularly important for investigating the relationship between nuclear activity and the galactic "eco-system".
