Abstract: 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 towards
high redshift quasars with the idea of detecting the BAO also in
the clustering of gas responsible for the Lyman alpha absorption present
in the quasars, known as the Lyman alpha forest.

In this talk I will present the fir ...
