[I was out Tuesday and Wednesday on travel.]
Spent a great day with Ben Weiner (Arizona) visiting. We discussed recent published and unpublished work on outflows from star-forming galaxies at redshifts 0.5 to 1.5. It looks like these are confirming the general view that feedback, and maybe AGN feedback, is important to shaping galaxies.
Weiner, Moustakas, Blanton, and I spent some time discussing measurements of the [O II] 3727 luminosity function, which I measured years ago. This could be done much better now, with far more galaxies and much better redshift coverage. Whenever this comes up, we ask "what's the point?", but Weiner and Moustakas both gave very convincing arguments that it is worthwhile. Now would someone please measure it?
