Résumé |
I will present the stage-IV Dark Energy Spectroscopic Instrument (DESI). The scientific goals
of DESI on dark energy, redshift space distortions and constraints on inflation or neutrino
mass will be compared to current measurements and limits set by ongoing experiments, in
particular by the SDSS BOSS and eBOSS projects. I will illustrate the construction status of
DESI, which is nearing completion, and give the timeline of the five-year survey. The project
has successfully observed its first spectroscopic light and is now under commissioning. When
it will enter survey mode, DESI is expected to be one of the world’s best facilities for wide-
field spectroscopy throughout the decade. |
