Description

Author and Presenter: James Rohlf
Abstract: The latest baryon acoustic oscillation (BAO) measurements from the Dark Energy Spectroscopic Instrument (DESI) are presented, based on three years of operation. The DESI only results are well described by a flat ΛCDM model, but the parameters preferred by BAO are in mild tension with those determined from the cosmic microwave background (CMB). This tension is alleviated with a time-evolving dark energy. Various scenarios and data combinations are discussed relating to the dark energy density, the Hubble parameter, and neutrino masses.
