论文摘要
在文献中已经表明，二进制来源发出的重力波（GWS）的检测可以提供亮度距离的测量。然后，随后发生电磁对应物的事件，适用于探测距离红移关系和进行宇宙学参数估计，并研究了修饰的重力（MG）模型。在与Horndeski相当的有效方法的背景下，由于波传播中存在修饰的摩擦，该GW距离与标准电磁光度距离不同。在这里，我们研究了未来计划的干涉仪爱因斯坦望远镜如何探究与一般相对性的这种偏差，考虑了状态和GW摩擦的暗能量方程的现象学参数化。尽管对重力进行了独立的测试，但特别是对于$ f（r）$，我们得出的结论可能会提供比当前可用的限制更弱的约束。
It has been shown in the literature that detections of gravitational waves (GWs) emitted by binary sources can provide measurements of luminosity distance. The events followed by electromagnetic counterparts are, then, suitable for probing the distance-redshift relation and doing cosmological parameter estimation, as well as investigating modified gravity (MG) models. In the context of effective approaches to MG equivalent to Horndeski, this GW distance differs from the standard electromagnetic luminosity distance due to the presence of a modified friction in the wave propagation. Here, we investigate how precisely the future-planned interferometer Einstein Telescope will probe such deviations from General Relativity, considering phenomenological parametrizations for both the dark energy equation of state and the GW friction. Despite being an independent test of gravity, for $f(R)$ in particular, we conclude that it may provide weaker constraints than the current available ones.
