摘要
分赫兹干涉引力波天文台（DECIGO）是日本未来的空间任务，频段为 0.1 Hz 至 10 Hz。DECIGO 旨在探测原初引力波，其可能产生于宇宙诞生后不久的暴胀时期。DECIGO 还有许多其他科学目标，包括直接测量宇宙膨胀的加速度，以及对中子星/黑洞双星并合的时间和位置做出可靠而准确的预测。DECIGO 由放置在日心轨道上的四组观测站组成。每组由三颗航天器构成，形成臂长为 1000 km 的三个法布里-珀罗迈克尔逊干涉仪。DECIGO 的三组将彼此远离放置，第四组将放置在与三组之一相同的位置，以获取用于探测原初引力波的相关信号。我们计划在 2030 年代 DECIGO 之前发射 B-DECIGO，它是 DECIGO 的科学探路者，以验证 DECIGO 所需的技术，并获得丰硕的科学成果以进一步拓展多信使天文学。
