论文摘要
GW170817和GRB 170817A的联合检测打开了具有引力波（GWS）的多门机天文学时代，并提供了第一个直接的直接探测，即至少一些二进制中子星（BNS）合并是短伽马射线爆发的祖细胞（S-GRB）。在接下来的几年中，由于GW探测器的灵敏度越来越高，我们预计将有更多的BNS合并探测。在这里，我们介绍了一项关于联合GW和电磁观察的前景的全面研究，该观察结果是在第四个Ligo-virgo-virgo-kagra中使用\ Emph {fermi}，\ emph {swift {swift}，intemal and intemal and svom。这项工作将准确的种群综合模型与预期的GW信号和相关的S-GRB结合在一起，考虑了对GRB射流结构的不同假设。我们表明，当考虑\ emph {fermi}/gbm时，我们可以最多可达$ \ sim $ 6 yr $^{ - 1} $的联合GW和电磁检测的预期速率。未来的联合观察将有助于我们更好地限制BNS合并与S-GRB之间的关联，以及GRB喷气机的几何形状。
The joint detection of GW170817 and GRB 170817A opened the era of multi-messenger astronomy with gravitational waves (GWs) and provided the first direct probe that at least some binary neutron star (BNS) mergers are progenitors of short gamma-ray bursts (S-GRBs). In the next years, we expect to have more multi-messenger detections of BNS mergers, thanks to the increasing sensitivity of GW detectors. Here, we present a comprehensive study on the prospects for joint GW and electromagnetic observations of merging BNSs in the fourth LIGO--Virgo--KAGRA observing run with \emph{Fermi}, \emph{Swift}, INTEGRAL and SVOM. This work combines accurate population synthesis models with simulations of the expected GW signals and the associated S-GRBs, considering different assumptions about the GRB jet structure. We show that the expected rate of joint GW and electromagnetic detections could be up to $\sim$ 6 yr$^{-1}$ when \emph{Fermi}/GBM is considered. Future joint observations will help us to better constrain the association between BNS mergers and S-GRBs, as well as the geometry of the GRB jets.
