论文摘要
对紧凑型二元合并的多通间观察有望巨大的科学宝藏。但是,引力波和电磁通道的合成观察仍然具有挑战性。 GW170817依靠日常的大分子发射,仍然是唯一成功进行电磁随访的事件。在此手稿中,我们探索了使用早期X射线余辉的可能性,以搜索引力波事件的电磁对应物。两种算法,即顺序观察和局部优化,并应用于三个模拟事件。我们将提出的爱因斯坦探针视为候选X射线望远镜。从庞大的视野和高灵敏度中受益,我们发现顺序观察算法不仅易于实现,而且还有望获得实际检测的机会。
The multi-messenger observation of compact binary coalescence promises great scientific treasure. However, a synthetic observation from both gravitational wave and electromagnetic channels remains challenging. Relying on the day-to-week long macronova emission, GW170817 remains the only event with successful electromagnetic followup. In this manuscript, we explore the possibility of using the early stage X-ray afterglow to search for the electromagnetic counterpart of gravitational wave events. Two algorithms, the sequential observation and the local optimization are considered and applied to three simulated events. We consider the proposed Einstein probe as a candidate X-ray telescope. Benefiting from the large field of view and high sensitivity, we find that the sequential observation algorithm not only is easy to implement, but also promises a good chance of actual detection.
