merging

Dan McIntosh (UMass) gave a nice group meeting talk on galaxy mergers in SDSS as a function of mass, mass ratio, and environment. During the talk I think we all realized that measures of the merger rate are in some sense more precise measures of galaxy evolution than measures of the differences between different redshifts, but they are not necessarily more accurate because they involve substantial uncertainties in their interpretation.
