Abstract:

The Dark Energy Spectroscopic Instrument (DESI) is a massivelymultiplexed fiber-fed spectrograph that will make the next major advancein dark energy in the timeframe 2018-2022. On the Mayall telescope, DESIwill obtain spectra and redshifts for at least 18 million emission-linegalaxies, 4 million luminous red galaxies and 3 million quasi-stellarobjects, in order to: probe the effects of dark energy on the expansionhistory using baryon acoustic oscillations (BAO), measure thegravitational growth history through redshift-space distortions, measurethe sum of neutrino masses, and investigate the signatures of primordialinflation. The resulting 3-D galaxy maps at z<2 and Lyman-alpha
