Cosmology from Three Years of DESI Spectroscopy

by Prof. Kyle Dawson (Univ. of Utah)

Tuesday May 6, 2025, 3:30 PM → 5:30 PM US/Eastern

Over a five-year period, the Dark Energy Spectroscopic Instrument (DESI) will spectroscopically classify nearly 40 million galaxies and quasars over 1/3 of the sky and to redshifts z < 3.5. The DESI collaboration has completed measurements of the baryon acoustic oscillation (BAO) feature and more generally, of large-scale structure, using data from the first three years of observation. In this talk, I will present those measurements and their implications for our understanding of the cosmological model. In doing so, I will discuss the DESI measurements with respect to the hints of tension that have been reported in the Hubble Constant and with LCDM.
