recursion, infrared lines

Among other things, Schiminovich and I wrote a recursive program to construct a hierarchical tree of voxels in a high dimensional space. This is just to make a good binning of the quasars that we are using to study the clustering of extinction and lyman alpha opacity. I only mention it here because we found the logic of the recursion so challenging!

Wu finished measuring the narrow emission lines in our Spitzer high-resolution mid-infrared spectroscopy of normal SDSS galaxies. It looks like the line phenomenology is going to be rich, and that we can measure molecular masses, star formation rates, and ionization spectrum independently from or differently than in the visible SDSS spectra.
