论文摘要
包括Lisa，Taiji和Tianqin在内的太空引力波（GW）探测器能够检测由超质量Black Hole Binaries合并产生的MHz GW信号，该信号为GW天文学打开了新的窗口。在本文中，我们使用贝叶斯分析从数值上估计了多个基于空间检测器的未来网络的潜在能力。我们修改了公共软件包Bilby，并采用了Sampler Pymultinest来分析空间基于空间的检测器网络的模拟数据，并研究了它们的能力来源定位和测试重力的奇偶校验对称性。与单个检测器相比，我们发现检测器网络可以显着改善源定位。在限制重力的奇偶校验对称性的同时，我们发现检测器网络和单个检测器遵循均衡能量尺度上的相似约束$ M _ {\ rm PV} $。类似的分析可以应用于各种空间GW检测器的其他潜在观察结果。
Space-based gravitational-wave (GW) detectors, including LISA, Taiji and TianQin, are able to detect mHz GW signals produced by mergers of supermassive black hole binaries, which opens a new window for GW astronomy. In this article, we numerically estimate the potential capabilities of the future networks of multiple space-based detectors using Bayesian analysis. We modify the public package Bilby and employ the sampler PyMultiNest to analyze the simulated data of the space-based detector networks, and investigate their abilities for source localization and testing the parity symmetry of gravity. In comparison with the case of an individual detector, we find detector networks can significantly improve the source localization. While for constraining the parity symmetry of gravity, we find that detector networks and an individual detector follow the similar constraints on the parity-violating energy scale $M_{\rm PV}$. Similar analysis can be applied to other potential observations of various space-based GW detectors.
