论文摘要
开发了参数化的后源形式主义，以寻找与重力波的一般相对性的通用偏差。我们在这里使用贝叶斯对一组二进制脉冲星观测的贝叶斯分析对此框架提出了限制。特别是，我们使用六个不同二元脉冲星系统的开普勒和后凯伯后参数的测量值，以及马尔可夫链蒙特 - 卡洛探索来计算参数化的后源后参数和衍生鲁棒约束的后代。相对于仅使用双二元脉冲星时，我们发现结合所有六个观测值时，我们发现约束强度的1-2个数量级的改善。我们还发现，与二进制组件质量的协方差相协方差。此处得出的参数化后的后代框架的界限可以用作未来的贝叶斯与重力波观测的一般相对性测试的先验测试。
The parameterized post-Einsteinian formalism was developed to search for generic deviations from general relativity with gravitational waves. We here present constraints on this framework using Bayesian analysis of a set of binary pulsar observations. In particular, we use measurements of the Keplerian and post-Keplerian parameters of six different binary pulsar systems, and Markov-Chain Monte-Carlo exploration to calculate posteriors on the parameterized post-Einsteinian parameters and derive robust constraints. We find improvements of 1-2 orders of magnitude in the strength of constraints when combining all six observations, relative to what one can achieve when using only the double binary pulsar. We also find that the constraints are robust to covariances with the binary's component masses. The bounds on the parameterized post-Einsteinian framework derived here could be used as a prior in future Bayesian tests of general relativity with gravitational wave observations.
