论文摘要
非圆轨道中的单个超质量黑洞二进制物是快速成熟的脉冲星定时阵列实验的纳米赫兹引力源。我们开发了一种准确，有效的方法来计算脉冲星时正时阵列信号，这是由于从相对论偏心轨道中的超级大质量黑洞二进制物引起的重力波。我们的方法采用开普勒型参数解决方案来模拟第三后牛顿后精确的预击偏心轨道，同时提供了新型的半分析处方，以模拟四极级重力引力波发射的影响。这些输入导致半分析的处方，以建模这种信号，该信号是由非旋转黑洞二进制组引起的，它沿任意偏心轨道启发了。此外，我们还提供了一个完全分析的处方，可为沿着中等偏心轨道的黑洞二进制器的模型脉冲星时阵列阵列信号提供，受Bootzelet Al。[Phys。 Rev.

Individual supermassive black hole binaries in non-circular orbits are possible nanohertz gravitational wave sources for the rapidly maturing Pulsar Timing Array experiments. We develop an accurate and efficient approach to compute Pulsar Timing Array signals due to gravitational waves from inspiraling supermassive black hole binaries in relativistic eccentric orbits. Our approach employs a Keplerian-type parametric solution to model third post-Newtonian accurate precessing eccentric orbits while a novel semi-analytic prescription is provided to model the effects of quadrupolar order gravitational wave emission. These inputs lead to a semi-analytic prescription to model such signals, induced by non-spinning black hole binaries inspiralling along arbitrary eccentricity orbits. Additionally, we provide a fully analytic prescription to model Pulsar Timing Array signals from black hole binaries inspiraling along moderately eccentric orbits, influenced by Boetzelet al.[Phys. Rev. D 96,044011(2017)]. These approaches are being incorporated into Enterprise and TEMPO2 for searching the presence of such binaries in Pulsar Timing Array datasets.
