标题： Cosmology in the dark: How compact binaries formation impact the gravitational-waves cosmological measurements

摘要： 在没有通过电磁(EM)观测获得红移测量的情况下，关于致密星体质量谱的信息可以用于从引力波(GW)中推断宇宙学参数。 这种方法将在当前和未来的地面引力波探测器中成为测量和检验宇宙学的基本手段，因为在这些探测器中大部分源都没有关联的电磁对应物。 在本文中，我们将讨论这种方法在研究宇宙学中的前景和局限性。 我们将展示，即使假设当前灵敏度的引力波探测器，哈勃常数的确定与黑洞产生的最大质量之间存在强烈的退化关系。 我们将讨论假设错误的黑洞事件基础种群模型如何将哈勃常数估计偏差高达40%。 显示英文摘要

摘要： Information about the mass spectrum of compact stars can be used to infer cosmological parameters from gravitational waves (GW) in the absence of redshift measurements obtained from electromagnetic (EM) observations. This method will be fundamental in measuring and testing cosmology with GWs for current and future ground-based GW detectors where the majority part of sources are detected without an associated EM counterpart. In this proceeding, we will discuss the prospects and limitations of this approach for studying cosmology. We will show that, even when assuming GW detectors with current sensitivities, the determination of the Hubble constant is strongly degenerate with the maximum mass for black hole production. We will discuss how assuming wrong models for the underlying population of black hole events can bias the Hubble constant estimate up to 40\%.
