一个先进的LIGO和处女座的第三次观测运行带来了另一次双中子星合并（BNS）和第一次中子星黑洞合并。虽然没有确认的千新星与这些事件有关，但围绕GW170817的持续改进分析使我们能够预测哈勃常数（h0）的限制，r过程核合成的银河系富集，以及即将发生的事件可能产生的超致密物质。本文基于国际引力波网络的最新预期事件率和对GW170817的分析，描述了预期约束条件。我们展示了引力波及其对应波的预期探测率，以及潜在约束对观测到的对应波的数量有多敏感。我们打算在创建科学驱动的电磁后续建议时，将此分析作为社区的支持。在下一次观测运行O4期间，我们预测Zwicky瞬变设施（Rubin天文台）的BNS电磁对偶体的年检出率为0.43−0.26+0.58（1.97−1.2+2.68）。
An advanced LIGO and Virgo’s third observing run brought another binary neutron star merger (BNS) and the first neutron-star black hole mergers. While no confirmed kilonovae were identified in conjunction with any of these events, continued improvements of analyses surrounding GW170817 allow us to project constraints on the Hubble Constant (H 0), the Galactic enrichment from r-process nucleosynthesis, and ultra-dense matter possible from forthcoming events. Here, we describe the expected constraints based on the latest expected event rates from the international gravitational-wave network and analyses of GW170817. We show the expected detection rate of gravitational waves and their counterparts, as well as how sensitive potential constraints are to the observed numbers of counterparts. We intend this analysis as support for the community when creating scientifically driven electromagnetic follow-up proposals. During the next observing run O4, we predict an annual detection rate of electromagnetic counterparts from BNS of 0.43−0.26+0.58 ( 1.97−1.2+2.68 ) for the Zwicky Transient Facility (Rubin Observatory).
