Early Results Using the Lyman-alpha Forest in DESI

The Dark Energy Spectroscopic Instrument (DESI) is a multi-object spectrograph on the 4-m Mayall Telescope at Kitt Peak National Observatory. The main goal of DESI is to measure with unprecedented precision the expansion history of the Universe with the Baryon Acoustic Oscillation (BAO) technique and the growth rate of structure with Redshift Space Distortions.

In this talk I will present initial results using the Lyman-alpha forest of high redshift quasars (z ~2-3) from the first two months of DESI data, and compare them with previous measurements.
