在银河系中心有一个PeVatron的假设，是随着H.E.S.S.最近的射线测量而出现的。[1]，激发了从这个来源寻找中微子的动机。射线吸收的影响进行了研究：在目前探测的能量，已知的背景辐射场导致小的影响，而它是不可能排除大的影响，由于新的红外辐射场附近的非常中心。精确的上限中微子通量的推导和基本假设进行了讨论。根据H.E.S.S.，ANTARES、IceCube和KM3NeT的预期事件数量。测量，计算。结果表明，在北方公里级的望远镜有可能观察到高能中微子从这个重要的天文对象，并可以检查强子PeV星系加速器的存在。
The hypothesis of a PeVatron in the Galactic Center, emerged with the recent-ray measurements of H.E.S.S. [1], motivates the search for neutrinos from this source. The effect of-ray absorption is studied: at the energies currently probed, the known background radiation fields lead to small effects, whereas it is not possible to exclude large effects due to new IR radiation fields near the very center. Precise upper limits on neutrino fluxes are derived and the underlying hypotheses are discussed. The expected number of events for ANTARES, IceCube and KM3NeT, based on the H.E.S.S. measurements, are calculated. It is shown that km-class telescopes in the Northern hemisphere have the potential of observing high-energy neutrinos from this important astronomical object and can check the existence of a hadronic PeV galactic accelerator.
