论文摘要
可以使用引力波观测检测到的二进制黑洞群体的质量和红移分布的关节拟合，可用于获得对哈勃参数的约束以及在引力波传播中偏离一般相对性的偏差。我们首先将该技术应用于最新的重力波事件目录，重点是比较黑洞二进制文件的不同参数化的源框架质量分布。我们发现，即使在改变宇宙学的情况下，数据受到了多个功能的模型，即使人口研究也是如此。然后，我们讨论使用该技术与第三代重力波检测器使用的观点，从而利用了最近开发的Fisher Information Matrix Python Code GWFAST。
A joint fit of the mass and redshift distributions of the population of Binary Black Holes detected with Gravitational-Wave observations can be used to obtain constraints on the Hubble parameter and on deviations from General Relativity in the propagation of Gravitational Waves. We first present applications of this technique to the latest catalog of Gravitational-Wave events, focusing on the comparison of different parametrizations for the source-frame mass distribution of Black Hole Binaries. We find that models with more than one feature are favourite by the data, as suggested by population studies, even when varying the cosmology. Then, we discuss perspectives for the use of this technique with third generation Gravitational-Wave detectors, exploiting the recently developed Fisher information matrix Python code GWFAST.
