SUMMARY:Gas accretion and star formation in disk galaxies
DESCRIPTION:Numerical simulations predict that metal-poor gas accretion from the cosmic web fuels the\nformation of disk galaxies. My presentation will summarize observational evidence\nfor this gas accretion process driving star formation. In particular\, I will discuss\na number of properties characterizing large samples of star-forming galaxies that\ncan be explained by metal-poor gas accretion (e.g.\, the fundamental metallicity relation\,\nor the relationship between galaxy morphology and metallicity). Some properties of the\n(neutral and ionized) gas around galaxies will be examined too. I will also review the\nproperties of the extremely metal poor galaxies. They show chemical and dynamical\ninhomogeneities that can be naturally explained as due to star-formation feeding from\ninfall of external metal-poor gas.
