论文摘要
恒星质量的二进制黑洞将扫过激光干涉仪空间天线（LISA）的频带数月至几年，然后出现在地面重力波检测器的音频带中。人们可以期望每年$ 500 \，\ mathrm {mpc} $的几十个事件。即使在这些近距离距离处，丽莎的信噪比也将太小，无法自信地检测到它们。但是，下一代地面的重力波检测器预计在丽莎（Lisa）时将其运行，将以数千个的信噪比观察它们，并非常准确地测量其参数。我们表明，通过基于地面检测器对这些来源进行如此高的忠诚度观察，有助于每年从LISA数据中挖出数十个信号。
Stellar-mass binary black holes will sweep through the frequency band of the Laser Interferometer Space Antenna (LISA) for months to years before appearing in the audio-band of ground-based gravitational-wave detectors. One can expect several tens of these events up to a distance of $500 \,\mathrm{Mpc}$ each year. The LISA signal-to-noise ratio for such sources even at these close distances will be too small for a blind search to confidently detect them. However, next generation ground-based gravitational-wave detectors, expected to be operational at the time of LISA, will observe them with signal-to-noise ratios of several thousands and measure their parameters very accurately. We show that such high fidelity observations of these sources by ground-based detectors help in archival searches to dig tens of signals out of LISA data each year.
