摘要
2021 年 5 月，暗能量光谱仪器（DESI）合作组开始了一项为期 5 年的光谱红移巡天，以产生 z=0 到 z≈4 之间宇宙三维演化结构的详细图谱。DESI 的主要科学目标是对暗能量的状态方程、引力驱动的大尺度结构增长以及中微子总质量施加精确约束，并探索原初暴涨的观测特征。我们介绍了 DESI 数据发布 1（DR1），它包含 DESI 主巡天前 13 个月获取的所有数据，以及 DESI 巡天验证数据的统一再处理，该数据此前已在 DESI 早期数据发布中公开。DR1 主巡天包括 1870 万个天体的高置信度红移，其中 1310 万个被光谱分类为星系，160 万个为类星体，400 万个为恒星，使 DR1 成为有史以来最大的河外红移样本。我们总结了 DR1 的观测、光谱数据缩减流程和数据产品、大尺度结构星表、增值星表，并描述了如何访问和交互这些数据。除了以前所未有的精度完成其核心宇宙学目标外，我们期望 DR1 能够支持广泛的变革性天体物理研究和发现。
