AI总结:

本文基于Friedmann宇宙学模型,推导出引力波与电磁波光度距离之间的通用多信使一致性条件,探讨了平坦性假设对宇宙学参数估计的影响,并提出了不依赖暗能量方程状态的通用多信使一致性关系。

摘要:

我们证明在Friedmann宇宙学模型框架内,可以推导出引力波(GW)和电磁波(EMW)光度距离之间的通用多信使一致性条件。我们首先研究了在GW观测中常用于估计宇宙学参数的平坦性假设的影响,推导出一个仅用平坦性偏倚的GW和EMW光度距离表示的曲率参数一般关系,并推导出适用于Friedmann模型的多信使一致性关系,其不依赖于暗能量方程状态。然后我们推导出一个通用的多信使一致性关系用于宇宙学常数,该关系不依赖于分析观测数据时所作的任何平坦性假设。

英文摘要:

We show that within the framework of the Friedmann cosmological model it is possible to derive general multimessenger consistency conditions, between the gravitational wave (GW) and the electromagnetic wave (EMW) luminosity distances. We first study the effects of the flatness assumption often used in the estimation of cosmological parameters from GWs observations, deriving a general relation for the curvature parameter, uniquely in terms of the flatness biased GW and the EMW luminosity distances, and a multimessenger consistency relation for the Friedmann model, valid independently of the dark energy equation of state. We then derive a general multimessenger consistency relation for the cosmological constant, which is independent of any flatness assumption made in the analysis of observational data.
