Abstract
The Dark Energy Spectroscopic Instrument (DESI) is conducting an 8 year redshift survey of more than 60 million extra-galactic sources over 17,000 square degrees. One of its primary goals is to measure the cosmic expansion history across a wide range of redshifts in order to probe the nature of dark energy. At high redshifts (z > 2), DESI uses the Lyman-alpha forest and its cross-correlation with the quasar distribution to map the underlying large-scale structure and constrain cosmology. In this talk, I will present the latest results from the DESI Lyman-alpha forest sample. These include full-shape measurements of the Lyman-alpha forest and their cosmological interpretation.
