标题： Impacts of the simulated standard siren on estimating cosmological parameters

摘要： 我们提出一种基于从引力波（GW）信号中提取引力波参数的过程来模拟双中子星（BNS）合并事件的方法。我们基于爱因斯坦望远镜（ET）的观测模拟了1000个GW标准汽笛。几乎所有的模拟GW数据都处于红移范围$[0,3]$内。研究了GW标准汽笛在宇宙学参数推断中的作用。我们发现GW数据有助于提高宇宙学参数的准确性。此外，GW数据打破了宇宙学参数的简并性。GW标准汽笛有助于对宇宙学参数的约束。 显示英文摘要

摘要： We propose a method based on the process of extracting gravitational wave (GW) parameters from GW signals to simulate the binary neutron-star (BNS) merging events. We simulate 1000 GW standard sirens based on the observation of the Einstein Telescope (ET). Almost all the simulated GW data are in the redshift range of $[0,3]$. The role of the GW standard siren in the inference of the cosmological parameters is investigated. We find that the GW data can help improve the accuracy of cosmological parameters. Moreover, the degeneracy of cosmological parameters is broken by the GW data. The GW standard siren is helpful for the constraint of the cosmological parameters.
