量化候选多信使宇宙事件探测的重要性是天体物理学和天文学界的一个新兴需求。在本文中，我们证明了与模型无关的最优搜索并不存在，并且我们提出了一种用于模型相关的最优搜索的通用贝叶斯方法，该方法可扩展到任何数量和任何类型的信使，并且适用于任何模型。最后，我们通过引力波、高能中微子、短伽马暴事件联合搜索的例子进行论证；迄今为止尚未经过审查。
Quantification of the significance of a candidate multi-messenger detection of cosmic events is an emerging need in the astrophysics and astronomy communities. In this paper we show that a model-independent optimal search does not exist, and we present a general Bayesian method for the optimal model-dependent search, which is scalable to any number and any kind of messengers, and applicable to any model. In the end, we demonstrate it through an example for a joint gravitational wave, high-energy neutrino, short gamma-ray burst event search; which has not been examined heretofore.
