The Dark Energy Spectroscopic Instrument (DESI) Collaboration is an international scientific collaboration focused on mapping the expansion of the universe to understand the mysterious force known as dark energy, which is believed to be driving the acceleration of the universe’s expansion. The collaboration utilizes the DESI instrument, mounted on the Mayall 4-meter telescope at Kitt Peak National Observatory in Arizona, USA. This advanced spectroscopic instrument, which began its survey in 2020, is designed to measure the redshifts of tens of millions of galaxies and quasars, covering a third of the sky. By analyzing the distribution and movement of these celestial objects over vast distances and time periods, DESI aims to provide precise measurements of the effects of dark energy and to improve our understanding of cosmology, including the overall matter content of the universe and the scale of cosmic structures.
