论文摘要
中子星 - 黑洞（NSBH）合并的引力波（GW）和电磁（EM）观察可以提供哈勃常数（$ H_0 $）的精确局部测量值，非常适合解决当前$ H_0 $张力。我们对模拟NSBH的现实种群进行端到端分析，首次融合了GW和EM选择。我们表明，NSBHS可以在2030年达到公正的1.5-2.4％精度$ H_0 $估计。可实现的精度受到旋转进动和潮汐破坏的细节的强烈影响，突显了改进NSBH合并建模的需求。
Gravitational wave (GW) and electromagnetic (EM) observations of neutron-star-black-hole (NSBH) mergers can provide precise local measurements of the Hubble constant ($H_0$), ideal for resolving the current $H_0$ tension. We perform end-to-end analyses of realistic populations of simulated NSBHs, incorporating both GW and EM selection for the first time. We show that NSBHs could achieve unbiased 1.5-2.4% precision $H_0$ estimates by 2030. The achievable precision is strongly affected by the details of spin precession and tidal disruption, highlighting the need for improved modeling of NSBH mergers.
