从GW 150914的高级LIGO探测中推断出的黑洞二元体（BHB）合并率意味着，演化激光干涉仪空间天线（eLISA）可以访问毫赫兹频率的异常响亮的引力波（GW）天空，并产生了几个突出的后果。首先，多达数千个BHB将被eLISA单独分辨;其次，数百万个不可分辨的BHB将建立一个可检测的混淆噪声，信噪比为几到几百;第三，也许是最重要的，多达数百个可被eLISA单独分辨的BHB将在10年内合并在先进的LIGO波段。eLISA观测将提前几周告诉Advanced LIGO和所有电磁探测器这些BHB合并将在何时何地发生，其不确定性为
The black hole binary (BHB) coalescence rates inferred from the Advanced LIGO detection of GW150914 imply an unexpectedly loud gravitational-wave (GW) sky at millihertz frequencies accessible to the Evolved Laser Interferometer Space Antenna (eLISA), with several outstanding consequences. First, up to thousands of BHBs will be individually resolvable by eLISA; second, millions of nonresolvable BHBs will build a confusion noise detectable with a signal-to-noise ratio of a few to hundreds; third-and perhaps most importantly-up to hundreds of BHBs individually resolvable by eLISA will coalesce in the Advanced LIGO band within 10 y. eLISA observations will tell Advanced LIGO and all electromagnetic probes weeks in advance when and where these BHB coalescences will occur, with uncertainties of
