我们研究了观测高能宇宙τ中微子（$E_{\nu} \sim 10^{6}$GeV）的前景，这些中微子源于活动星系核核心的质子加速过程。我们考虑了真空味中微子振荡导致τ中微子与μ中微子通量比大大超过由内禀产生所预期的相当小的值的可能性。通过考虑可能通过特征性双簇射事件探测下行的高能宇宙τ中微子，给出了水下或冰中切伦科夫中微子望远镜的标准和事件率。
We study the prospects for the observation of high-energy cosmic tau neutrinos $(Eg~{10}^{6}$ GeV) originating from proton acceleration in the cores of active galactic nuclei. We consider the possibility that vacuum flavor neutrino oscillations induce a tau to muon neutrino flux ratio greatly exceeding the rather small value expected from intrinsic production. The criteria and event rates for under water or ice light \ifmmode \check{C}\else \v{C}\fi{}erenkov neutrino telescopes are given by considering the possible detection of downgoing high-energy cosmic tau neutrinos through characteristic double shower events.
