论文摘要
在标准宇宙学场景之外，电磁和重力波源的亮度距离估计在动态暗能和重力模型中通常是不同的。我们表明，这在重力波观测的光度距离的波动距离上留下了独特的烙印，该镜头跟踪了黑暗能量场中的不均匀性。利用超新星和引力波距离测量值的协同作用，我们建立了一个关节估计器，该估计值直接探测暗能量波动，为检测到它们的存在提供了确定的证据。此外，这种测量也将允许探测普朗克质量的运行。我们讨论检测这些信号的实验要求。
Luminosity distance estimates from electromagnetic and gravitational wave sources are generally different in models of dynamical dark energy and gravity beyond the standard cosmological scenario. We show that this leaves a unique imprint on the angular power-spectrum of fluctuations of the luminosity distance of gravitational-wave observations which tracks inhomogeneities in the dark energy field. Exploiting the synergy in supernovae and gravitational wave distance measurements, we build a joint estimator that directly probes dark energy fluctuations, providing a conclusive evidence for their existence in case of detection. Moreover, such measurement would also allow to probe the running of the Planck mass. We discuss experimental requirements to detect these signals.
