摘要
LiteBIRD，即用于通过宇宙背景辐射探测研究 B 模偏振与暴胀的轻量（Lite）卫星，是一项针对原初宇宙学与基础物理的空间任务。日本宇宙航空研究开发机构（JAXA）于 2019 年 5 月将 LiteBIRD 选为战略大型（L 级）任务，预计在 2020 年代后期使用 JAXA 的 H3 火箭发射。LiteBIRD 计划绕日地拉格朗日点 L2 运行，在那里它将用三年时间、以 34 至 448 GHz 之间 15 个频带的三个望远镜，绘制全天宇宙微波背景（CMB）偏振图，以实现前所未有的 2.2K-arcmin 总灵敏度，在 100 GHz 处典型角分辨率为 0.5。LiteBIRD 的主要科学目标是搜寻宇宙暴胀的信号， either making a discovery or ruling out well-motivated inflationary models。LiteBIRD 的观测还将为我们提供关于引力的量子性质以及超出粒子物理与宇宙学标准模型的其他新物理的见解。我们概述了 LiteBIRD 项目，包括科学目标、任务与系统需求、运行概念、航天器与载荷舱设计、预期科学成果、潜在设计扩展以及与其他项目的协同。
