论文摘要
超级质量黑洞二进制系统（SMBHB）发射引力波可以通过周期性光曲线来追溯。我们组装了一个149个这样的周期光曲线的目录，并使用它们的质量，距离和周期来预测每个二元候选者的重力波应变，并使用全天空检测图。我们发现，国际Pulsar定时阵列（IPTA）提供了几乎均匀的天空覆盖范围 - IPTA的独特能力 - 到2025年，Nanograv的当前最小可检测应力将提高6倍，其体积增加了216倍。此外，IPTA将在20255和13的范围内达到三个候选人的敏感性。用于估计SMBH质量。我们发现，实际上我们已经可以将MRK 504中的二进制质量限制为$ m <3.3 \ times 10^9〜m_ \ odot $。我们还确定了24个高质量高速度星系，根据我们的模型，这些星系应该无法托管SMBHB。重要的是，即使是这些候选者之一的GW检测将是一个实质上是永恒的多通用器系统，并且从非检测中识别常见的误报信号对于从未来的大规模调查（例如LSST）（例如LSST）中过滤数据将很有用。
Supermassive black hole binary systems (SMBHBs) emitting gravitational waves may be traced by periodic light curves. We assembled a catalog of 149 such periodic light curves, and using their masses, distances, and periods, predicted the gravitational-wave strain and detectability of each binary candidate using all-sky detection maps. We found that the International Pulsar Timing Array (IPTA) provides almost uniform sky coverage -- a unique ability of the IPTA -- and by 2025 will improve NANOGrav's current minimum detectable strain by a factor of 6, and its volume by a factor of 216. Moreover, IPTA will reach detection sensitivities for three candidates by 2025, and 13 by the end of the decade, enabling us to constrain the underlying empirical relations used to estimate SMBH masses. We find that we can in fact already constrain the mass of a binary in Mrk 504 to $M<3.3\times 10^9~M_\odot$. We also identify 24 high-mass high-redshift galaxies which, according to our models, should not be able to host SMBHBs. Importantly the GW detection of even one of these candidates would be an essentially eternal multimessenger system, and identifying common false positive signals from non-detections will be useful to filter the data from future large-scale surveys such as LSST.
