Unraveling the Universe with DESI

Understand

The Dark Energy Spectroscopic Instrument (DESI) is a stage IV ground-based dark energy experiment planned to begin operations in 2020.

• In this article, we provided a short review of DESI presented during the conference {\it Recontres de Moriond 2018}.
• DESI will use four different tracers for mapping the universe: from redshift 0.05 up to redshift 1.7 with galaxies and from 2.1 to 3.5 using quasars.
• DESI will measure a total of 35 million spectra covering regions of universe never explored before, providing a map of large scale structure that will enable major advances in the investigation of cosmic acceleration.
