The Dark Energy Spectroscopic Instrument (DESI)
Abstract
We present the status of the Dark Energy Spectroscopic Instrument (DESI) and its plans and opportunities for the coming decade. DESI is an approved experiment of the U.S. Department of Energy. Beyond 2025, we expect that DESI will remain one of the world's best facilities for wide-field spectroscopy throughout the decade.
