Description
DESI has started its observation program since May 2021. It has demonstrated its ability to complete its program in less than 5 years. From 2025 will begin a phase of transition which will finish in 2028 with DESI-II.
DESI-II will have for first objective to cover a zone in redshift little covered by DESI, in the 2<z<4 range. We will use as tracers of the matter, Lyman-Break Galaxies. The second goal of DESI-II will be to propose at lower redshift, typically 0<z<1, a survey of Luminous Red Galaxies, at very high densities.
I will present the scientific program of DESI-II and the upgrades of the instrument that are also planned.
