Simulations on how minor mergers can explain the variation in UV-fluxes of ellipticals.

They say they cannot “rule out” gas accretion, but I wonder where the dividing line goes between a gas-rich dwarf being eaten and infall of gas.

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
