Cosmology from the First Year DESI BAO Measurements

Join an astrophysics colloquium lecture exploring groundbreaking findings from the Dark Energy Spectroscopic Instrument's (DESI) first year of observations. Delve into the analysis of baryon acoustic oscillation measurements and large-scale structure data collected from nearly 40 million galaxies and quasars across one-third of the sky. Learn how these observations contribute to our understanding of fundamental cosmological parameters, including the Hubble Constant, dark energy equation of state, and neutrino mass measurements. Examine the implications of these findings in relation to reported tensions with the Lambda Cold Dark Matter (LCDM) model and current Hubble Constant measurements. Presented by Kyle Dawson from the University of Utah at the Institute for Advanced Study/Princeton University Joint Astrophysics Colloquium, gain insights into how DESI's five-year mission is reshaping our understanding of the universe's structure and evolution.
