The Baryon Oscillations Spectroscopic Survey of SDSS-III has opened a new era for high-redshift large-scale structure surveys using spectra of intervening absorption. On large scales, the 3D redshift space linear power spectrum can be measured, as modified with two bias parameters for the Lyα forest, for density and peculiar velocity gradient. On small scales, the detailed physics of the...

The Baryon Oscillation Spectroscopic Survey (BOSS) uses the SDSS telescope to obtain spectra of 1.5 million galaxies to get a very accurate measurements of the BAO scale at redshift z ~0.5. Roughly a 20% of the fibers of the spectrograph, however, are pointing to high redshift quasars with the idea of detecting the BAO also in the clustering of gas responsible for the Lyα absorption present in...

We are currently in an exciting era of precision cosmology. With the release of the cosmic microwave background data recorded by the Planck satellite, we are now in a position to accurately test the standard model of Big Bang Nucleosynthesis. In this talk, I will present a new, precise measure of the primordial abundance of deuterium - the most accurate measurement to date - derived from a...
