论文摘要
来自中子恒星合并的重力波信号的有限大小影响通常在检测器灵敏度降低的高频下表现出来。提出的敏感性改善可以使我们访问更强的信号，也可以从宇宙学距离中获得无数弱信号。后者的数量将超过前者，并且信号的相关部分将被向探测器最敏感的频带进行红移。我们研究了有关中子恒星物质信息的红移依赖性，并发现单尺度属性（例如星形半径或合并后频率）可以从$ z \ sim 1 $的遥远弱源中更好地测量。
Finite-size effects on the gravitational wave signal from a neutron star merger typically manifest at high frequencies where detector sensitivity decreases. Proposed sensitivity improvements can give us access both to stronger signals and to a myriad of weak signals from cosmological distances. The latter will outnumber the former and the relevant part of signal will be redshifted towards the detector most sensitive band. We study the redshift dependence of information about neutron star matter and find that single-scale properties, such as the star radius or the post-merger frequency, are better measured from the distant weak sources from $z\sim 1$.
