Resum:

BOSS (Baryon Oscillations Spectroscopic Survey) was a premier spectroscopic experiment for cosmology that has recently completed its observational program. It has measured spectra of nearly 2 million objects spanning significant amounts of the total cosmic volume. I will discuss how we constrain properties of the Universe using two tracers of large scale structure measured by BOSS: galaxies and Lyman-alpha forest. I will show recent results on cosmology observables, including neutrino masses and properties of dark energy. I will conclude by briefly discussing open questions and future experiments.
