Summary
The Dark Energy Spectroscopic Instrument (DESI) installed on the Nicholas U. Mayall 4-metre Telescope at Kitt Peak National Observatory near Tucson, Arizona. DESI is the most powerful multi-object survey spectrograph in the world; it maps the expansion history of the universe and the growth of cosmic structure by measuring the redshifts of tens of millions of galaxies and quasars.
