使用 ANTARES 中微子望远镜在 2007 年初至 2015 年底期间收集的数据对宇宙中微子源进行了搜索。 ANTARES 探测器首次在搜索点状源时考虑了所有中微子相互作用（所有类型的带电和中性电流相互作用）。在之前的分析中，仅使用μ子中微子带电电流相互作用。除了标准的μ子轨道重建之外，这是通过使用一种新颖的类似阵雨事件的重建算法来实现的。对于 E-2 能谱，簇射通道贡献了大约 23% 的所有信号事件。没有发现超过背景的显着过量。最像信号的事件簇位于 (α,δ)=(343.8°,23.5°) 处，显着性为 1.9σ。对于偏角从-90°到-42°，搜索的中微子通量灵敏度约为E2dΦ/dE=6×10-9 GeV cm-2 s-1，对于偏角高达5°的中微子通量灵敏度低于10-8 GeV cm-2 s-1。研究了来自 IceCube 高能样本事件的 106 个候选源和 13 个 μ 子径迹事件的方向，以寻找可能的中微子信号，并确定了信号通量的上限。
A search for cosmic neutrino sources using the data collected with the ANTARES neutrino telescope between early 2007 and the end of 2015 is performed. For the first time, all neutrino interactions—charged- and neutral-current interactions of all flavors—are considered in a search for point-like sources with the ANTARES detector. In previous analyses, only muon neutrino charged-current interactions were used. This is achieved by using a novel reconstruction algorithm for shower-like events in addition to the standard muon track reconstruction. The shower channel contributes about 23% of all signal events for an E-2 energy spectrum. No significant excess over background is found. The most signal-like cluster of events is located at (α,δ)=(343.8°,23.5°) with a significance of 1.9σ. The neutrino flux sensitivity of the search is about E2dΦ/dE=6×10-9 GeV cm-2 s-1 for declinations from -90° up to -42°, and below 10-8 GeV cm-2 s-1 for declinations up to 5°. The directions of 106 source candidates and 13 muon track events from the IceCube high-energy sample events are investigated for a possible neutrino signal and upper limits on the signal flux are determined.
