Today was devoted to an NSF proposal, which, according to the rules, is not research. The only research activity of the day was a talk by Nadia Zakamska (IAS) about infrared emission lines and what they have to say about the physics of galaxies. She has some beautiful results, especially that the PAH emission and the H2 emission in the interstellar medium are differently affected by dust extinction. This is odd, because they are both strongly correlated with star formation and one another. So they are strongly correlated but not co-spatial. Odd.
