即将到来的激光干涉仪空间天线（LISA）将探测到银河系白矮星双星的巨大引力波前景。这些信号源的特殊之处在于它们可能在电磁波长上被探测到，有些早在relisafly出现之前。对引力波和电磁波的研究将产生对系统参数的强烈约束，这是通过单独测量一个信使无法实现的。在这项工作中，我们提出了一个贝叶斯推理管道和仿真套件，其中我们研究了各种配置下二进制文件的潜在约束。我们展示了如何使用lisadetection和参数估计，当用作电磁分析的先验时，可以显着改善系统参数的约束。我们还提供了经验法则，说明当前的测量将如何从将来的mlismeasurements中受益。
The upcomingLaser Interferometer Space Antenna(LISA) will detect a large gravitational-wave foreground of Galactic white dwarf binaries. These sources are exceptional for their probable detection at electromagnetic wavelengths, some long beforeLISAflies. Studies in both gravitational and electromagnetic waves will yield strong constraints on system parameters not achievable through measurements of one messenger alone. In this work, we present a Bayesian inference pipeline and simulation suite in which we study potential constraints on binaries in a variety of configurations. We show how usingLISAdetections and parameter estimation can significantly improve constraints on system parameters when used as a prior for the electromagnetic analyses. We also provide rules of thumb for how current measurements will benefit fromLISAmeasurements in the future.
