Nikhil Padmanabhan (Berkeley) showed up at NYU today, and we discussed various matters related to BOSS and the baryon acoustic feature. Nikhil argued that we do not yet have a fully worked-out plan for analyzing the quasar absorption-line spectra, and measuring the correlation function therefrom. We discussed this in detail and I got a bit interested in the data analysis problem, which, when written down correctly, is quite difficult: It involves marginalizing over all hypotheses about each spectrum's unabsorbed continuum.
In other news, Surhud More submitted the transparency paper to ApJ. Should be on arXiv on Monday.
