摘要:

在过去的几年里,冰立方合作组织在几次分析中报告了对天体物理高能中微子事件的观测。尽管有令人信服的证据首次确认了中微子源TXS 0506+056,但大多数事件的起源仍然未知。本文利用ANTARES望远镜探测到的中微子事件,寻找冰立方天体物理事件的可能的瞬态起源。本文用极大似然方法对2346天探测到的6894个类径迹事件和160个类中微子事件的到达时间和方向进行了检验,以寻找与54个IceCube高能类径迹中微子事件的符合。没有观察到显着的相关性和上限的一种味道的中微子通量从冰立方候选人的方向推导出来。在0.1天的时间窗口内没有观测到两个能量最高的冰立方事件的时间和空间相关性,这限制了可能的点状瞬态中微子源的光谱指数,分别比每个事件的$-2.3$和$-2.4$更难。

英文摘要:

In the past years, the IceCube Collaboration has reported in several analyses the observation of astrophysical high-energy neutrino events. Despite a compelling evidence for the first identification of a neutrino source, TXS 0506+056, the origin of the majority of these events is still unknown. In this paper, a possible transient origin of the IceCube astrophysical events is searched for using neutrino events detected by the ANTARES telescope. The arrival time and direction of 6894 track-like and 160 shower-like events detected over 2346 days of livetime are examined to search for coincidences with 54 IceCube high-energy track-like neutrino events, by means of a maximum likelihood method. No significant correlation is observed and upper limits on the one-flavour neutrino fluence from the direction of the IceCube candidates are derived. The non-observation of time and space correlation within the time window of 0.1 days with the two most energetic IceCube events constrains the spectral index of a possible point-like transient neutrino source, to be harder than $-2.3$ and $-2.4$ for each event, respectively.
