Speaker
Description
The Dark Energy Spectroscopic Instrument (DESI) is a fiber-fed, robotically-actuated galaxy redshift survey that has been in operation at Kitt Peak National Observatory near Tucson, Arizona, USA since mid-2021. DESI, which observes the growth of structure from the nearby universe out to a redshift of 3, is currently producing the largest catalog of gravity redshifts ever assembled. With an order of magnitude more statistics than any previous redshift survey, the instrument is designed to provide sensitive constraints on dark energy, cosmic inflation, modified gravity, and the sum of the neutrino masses. In this talk, we describe the performance of the DESI instrument, the status of the survey, and future results.
