Dark Energy Spectroscopic Instrument Survey Data Release 1

ORAL · Invited

Abstract

We announce DESI Data Release 1 (DR1), the public release of all the data acquired by the Dark Energy Spectroscopic Instrument (DESI) Survey between December 2020 and June 2022. DR1 contains precise redshifts for more than 18.7M unique objects, including 13.1M galaxies, 1.6M quasars, and 4M stars, making DESI/DR1 larger than all previous spectroscopic redshift surveys combined. In this contribution, we showcase the DR1 data products and value-added catalogs, including the large-scale structure catalogs used for the DESI Year-1 cosmological results, and highlight how the community can access and interact with this exciting dataset.
