论文摘要

Deci-Hertz干涉仪重力波动台（Decigo）是未来的日本空间任务，其频带为0.1 Hz至10 Hz。 Decigo的目的是检测原始引力波，这可以在宇宙出生后的通货膨胀期间产生。 DECIGO还有许多其他科学目标，包括直接测量宇宙扩展的加速度，以及对中子星/黑洞二进制二进制结合的时间和位置的可靠和准确的预测。 Decigo由位于HeliePentric轨道中的四个观测值组组成。每个群集由三个航天器组成，它们形成三个Fabry-Perot Michelson干涉仪，臂长为1,000公里。将三个decigo的三个簇彼此放置，并且第四个集群将与三个簇之一的位置放置在相同的位置，以获得检测原始重力波的相关信号。我们计划在Decigo在2030年代的Decigo之前推出B-Decigo，这是Decigo的科学探路者，以展示Decigo所需的技术，并获得富有成果的科学成果，以进一步扩大多门徒的天文学。

Deci-hertz Interferometer Gravitational Wave Observatory (DECIGO) is the future Japanese space mission with a frequency band of 0.1 Hz to 10 Hz. DECIGO aims at the detection of primordial gravitational waves, which could be produced during the inflationary period right after the birth of the universe. There are many other scientific objectives of DECIGO, including the direct measurement of the acceleration of the expansion of the universe, and reliable and accurate predictions of the timing and locations of neutron star/black hole binary coalescences. DECIGO consists of four clusters of observatories placed in the heliocentric orbit. Each cluster consists of three spacecraft, which form three Fabry-Perot Michelson interferometers with an arm length of 1,000 km. Three clusters of DECIGO will be placed far from each other, and the fourth cluster will be placed in the same position as one of the three clusters to obtain the correlation signals for the detection of the primordial gravitational waves. We plan to launch B-DECIGO, which is a scientific pathfinder of DECIGO, before DECIGO in the 2030s to demonstrate the technologies required for DECIGO, as well as to obtain fruitful scientific results to further expand the multi-messenger astronomy.
