10.(Tie with 9) Stellar and Dark Matter Mass tell Galaxies When to Stop Forming stars

Why it is important: The observed bimodal color distribution of galaxies– either blue and star forming like our own spiral Milky Way galaxy, or ‘red and dead‘ (usually) like ellipticals– leads us to believe that something causes galaxies to evolve from gas-rich to gas-poor. Here, the authors look for trends in large galaxy samples to catch this evolution in the act.
