  • Dwarf galaxies: correlations between their global stellar and dynamical properties, such as circular velocity, mass-to-light ratio, stellar mass, surface brightness, and metallicity.
  • low and high z
  • simulation work
  • SN winds vs. ineficient SF
    • useful to compare to where our data fall on these correlations
