SDSS-III

Daniel Eisenstein (Arizona) was in for the day and we discussed SDSS-III, a project to follow the current phase of the Sloan Digital Sky Survey. NYU's main interest in SDSS-III is its project to measure the baryon acoustic feature at redshifts of 2/3 and 2.5 or so using luminous red galaxies and quasar absorption lines respectively. We are intending to contribute resources to the project in exchange for institutional participation and we will have some responsibility for the data analysis, data serving and sharing, archiving, and preservation. We spent most of our time working on what is needed for planning and budgeting, so it wasn't exactly a scientific morning. But that's research too, I guess!

In the afternoon I had a short but useful conversation with my colleague Scoccimarro about how best to measure the BAF given nonlinear evolution in the growth of structure at the scales of interest. He and Eisenstein disagree sharply on how to do this; I am confused because they are my two gurus on these subjects.
