nothing, baryons

I did no research today, although I had pretty good reasons for the failure!

Daniel Eisenstein gave a great talk at MIT on the baryon acoustic feature in large-scale structure (the subject of a paper we wrote together). He noted that a spectrograph on an 8-m class telescope that can take a few thousand spectra in a couple square degrees at a time can measure the baryon acoustic feature at redshift three (or one) in about a hundred good nights.

  1. Try it at redshift 2 - it will blow your mind!
