摘要

我们利用引力波（GW）瞬态目录3.0的数据更新了广义相对论（GR）参数化偏差的约束，这些偏差在伪复广义相对论（pcGR）理论和脏黑洞（BHs）模型中遇到。pcGR框架扩展了爱因斯坦的GR理论，引入了额外的参数，这些参数与强场的标准预测不同，可能会因为特定的参数选择而排除黑洞视界。我们分析了聚并致密物体的GW信号，得到了这些参数的新边界。我们的研究结果修正了现有的约束条件，并确定了先前未探索的参数空间区域，探索了脏黑洞和pcGR中无水平解的观测可行性。我们确认排除了足以避免视界的1PN偏差，并首次排除了1.5PN偏差。我们还讨论了改进这些约束条件对当前和未来GW观测的影响

Constraining dirty black holes and pseudo-complex general relativity with the gravitational waves transient catalog 3.0

We use data from the gravitational wave (GW) transient catalog 3.0 to update constraints on parameterized deviations from general relativity (GR), as encountered in pseudo-complex GR (pcGR) theory and models of dirty black holes (BHs). The pcGR framework extends Einstein’s theory of GR by introducing additional parameters that diverge from standard predictions in the strong-field regime, potentially excluding BH horizons for specific parameter choices. We analyze GW signals from coalescing compact objects to obtain new bounds on these parameters. Our results modify existing constraints and identify previously unexplored regions of parameter space, exploring the observational viability of dirty BHs and horizonless solutions in pcGR. We confirm the exclusion of 1PN deviations sufficient to avoid a horizon, and for the first time rule out 1.5PN as well. We also discuss implications for current and future GW observations in refining these constraints
