中子星星（NS）并合双星GW 170817的电磁对应物的发现开启了引力波多信使天文学的时代。光学/红外kilonova的快速识别使源的精确定位成为可能，这为深入的多波长后续工作及其无数相关科学成果铺平了道路。充分利用这一新的勘探领域需要从NS合并和其他引力波源的样品中获取电磁数据。在GW 170817之后，前沿现在是绘制千诺瓦性质的多样性，并对哈勃常数提供更严格的约束，并实现基础物理学的新测试。维拉C。鲁宾天文台的空间和时间遗产调查可以在2020年代在这一领域发挥关键作用，届时改进的引力波探测器网络预计将达到灵敏度，这将使发现涉及NS的合并事件的高速率（每年100万次）达到数百兆秒差距的距离。我们设计了全面的机会目标观测策略，用于跟踪引力波触发器，这将使鲁宾天文台成为发现和早期表征NS和其他致密天体合并以及未知类引力波事件的首要工具。
The discovery of the electromagnetic counterpart to the binary neutron star (NS) merger GW170817 has opened the era of gravitational-wave multimessenger astronomy. Rapid identification of the optical/infrared kilonova enabled a precise localization of the source, which paved the way to deep multiwavelength follow-up and its myriad of related science results. Fully exploiting this new territory of exploration requires the acquisition of electromagnetic data from samples of NS mergers and other gravitational-wave sources. After GW170817, the frontier is now to map the diversity of kilonova properties and provide more stringent constraints on the Hubble constant, and enable new tests of fundamental physics. The Vera C. Rubin Observatory’s Legacy Survey of Space and Time can play a key role in this field in the 2020s, when an improved network of gravitational-wave detectors is expected to reach a sensitivity that will enable the discovery of a high rate of merger events involving NSs (∼tens per year) out to distances of several hundred megaparsecs. We design comprehensive target-of-opportunity observing strategies for follow-up of gravitational-wave triggers that will make the Rubin Observatory the premier instrument for discovery and early characterization of NS and other compact-object mergers, and yet unknown classes of gravitational-wave events.
