​With the X-Shooter XQ-100 Legacy survey, 100 QSO measurements at intermediate resolutions were available to measure the Lyman-alpha power spectrum in the similar redshift range to SDSS (z=3 - 4.2), but to smaller scales (k_max ~ 6 h/Mpc). I will present these new results and comment on the data-analysis procedure. In the second part of the talk I will focus on using these new data (along with high-resolution high-redshift data) to put constraints on the cosmological and astrophysical parameters, and to review the constraints on the mass of a WDM particle as a DM candidate. I will also present the first constraints on the Fuzzy DM model using the same data set.
