论文摘要
在这封信中，我们表明，下一代地面观测值（3G）和太空激光干涉仪太空天线（LISA）对恒星质量二进制黑洞的多型观测将促进通过同时测量Newtonian后所有后（PN）系数的一般相对性。多频道观察结果将测量大多数已知的PN相位系数的精度，低于几个％---两个型号的命令比在3G或LISA频段中甚至从“黄金”二进制方面获得的最佳界限要好。这样的多参数界限将在约束超出一般相对性的重力理论的参数空间中起关键作用。
In this Letter we show that multiband observations of stellar-mass binary black holes by the next generation of ground-based observatories (3G) and the space-based Laser Interferometer Space Antenna (LISA) would facilitate a comprehensive test of general relativity by simultaneously measuring all the post-Newtonian (PN) coefficients. Multiband observations would measure most of the known PN phasing coefficients to an accuracy below a few percent---two orders-of-magnitude better than the best bounds achievable from even `golden' binaries in the 3G or LISA bands. Such multiparameter bounds would play a pivotal role in constraining the parameter space of modified theories of gravity beyond general relativity.
