We propose a space-based interferometer surveying the gravitational wave (GW) sky in the milli-Hz to μ-Hz frequency range. By the 2040s, the μ-Hz frequency band, bracketed in between the Laser Interferometer Space Antenna (LISA) and pulsar timing arrays, will constitute the largest gap in the coverage of the astrophysically relevant GW spectrum. Yet many outstanding questions related to astrophysics and cosmology are best answered by GW observations in this band. We show that a μ-Hz GW detector will be a truly overarching observatory for the scientific community at large, greatly extending the potential of LISA. Conceived to detect massive black hole binaries from their early inspiral with high signal-to-noise ratio, and low-frequency stellar binaries in the Galaxy, this instrument will be a cornerstone for multimessenger astronomy from the solar neighbourhood to the high-redshift Universe.

以 μHz 频率揭开引力宇宙的面纱

我们提出了一种天基干涉仪，用于测量毫赫兹到微赫兹频率范围内的引力波 (GW) 天空。到 2040 年代，包含在激光干涉仪空间天线 (LISA) 和脉冲星定时阵列之间的 μHz 频带将构成天体物理相关 GW 频谱覆盖范围的最大差距。然而，许多与天体物理学和宇宙学有关的悬而未决的问题都可以通过该波段的 GW 观测得到最好的回答。我们表明 μ-Hz GW 探测器将成为整个科学界真正的总体天文台，极大地扩展了 LISA 的潜力。设想从它们早期的高信噪比的螺旋中探测大质量黑洞双星，以及银河系中的低频双星，
