论文摘要

自重力波观测时代开始以来,就没有发现关节高能量中微子和重力波事件。这些非检测可用于将上微子发射特性上的上微子发射特性设置为重力波事件或其中一组。尽管在先前的关节高能量中微子和重力波事件搜索已被发现上限,但计算缺乏一致的方法。本文解决的问题是发现了天体物理事件的限制,这些限制位于天空中,中微子探测器的敏感性发生了很大变化,也可以发出中微子,例如引力波检测。在这里,我们描述了基于最大似然估计器的预期中微子计数,排放量和各向同性等效发射的限制的方法。然后,我们将描述的方法应用于Aligo的第一个观察跑(O1)的三个GW检测方法,并为其找到上限。

Since the start of the gravitational wave observation era, no joint high energy neutrino and gravitational wave event has been found. These non-detections could be used for setting an upper bound on the neutrino emission properties for gravitational wave events individually or for a set of them. Although in the previous joint high energy neutrino and gravitational wave event searches upper limits have been found, there is a lack of consistent method for the calculation. The problem addressed in this paper is finding those limits for astrophysical events which are localized poorly in the sky where the sensitivities of the neutrino detectors change significantly and can also emit neutrinos, for example the gravitational wave detections. Here we describe methods for assigning limits for expected neutrino count, emission fluence and isotropically equivalent emission based on maximum likelihood estimators. Then we apply described methods on the three GW detections from aLIGO's first observing run (O1) and find upper limits for them.
