论文摘要
计划的敏感性升级到Ligo和处女座设施可以唯一地识别黑色尖刻 - 紧凑型二进制二进制融合的宿主星系，而无需任何电磁的对应物与Z = 0.1的红移。这是由重力波信号中存在的高阶球形谐波模式的帮助，这也改善了距离估计。结合使用，灵敏度升级和较高的模式还将促进对宿主银河的红移进行准确，独立的测量，此外，从引力波观察的亮度距离来推断五年来的Hubble-Lema-常数H0至比几个百分之几。可能的旅行者升级或第三代设施将进一步巩固黑暗警报器在未来的精确宇宙学上的作用。
The planned sensitivity upgrades to the LIGO and Virgo facilities could uniquely identify host galaxies of dark sirens-compact binary coalescences without any electromagnetic counterparts-within a redshift of z = 0.1. This is aided by the higher order spherical harmonic modes present in the gravitational-wave signal, which also improve distance estimation. In conjunction, sensitivity upgrades and higher modes will facilitate an accurate, independent measurement of the host galaxy's redshift in addition to the luminosity distance from the gravitational wave observation to infer the Hubble-Lemaître constant H0 to better than a few percent in five years. A possible Voyager upgrade or third generation facilities would further solidify the role of dark sirens for precision cosmology in the future.
