标题： Identifying Galactic PeVatrons with Neutrinos

摘要： 我们对南极正在建设的千米级中微子探测器IceCube探测银河宇宙射线加速器方向中微子的潜力进行了现实评估。我们充分考虑了次级μ子能量测量可用于进一步区分信号与大气中微子背景这一事实。我们得出结论，IceCube可以在一年内以3σ置信水平、三年内以5σ置信水平将Milagro天图中的源识别为银河宇宙射线的来源。我们讨论了这些预期依赖于模糊性的程度，这些模糊性大多与我们对源天文学知识的不完善有关。 显示英文摘要

摘要： We perform a realistic evaluation of the potential of IceCube, a kilometer-scale neutrino detector under construction at the South Pole, to detect neutrinos in the direction of the potential accelerators of the Galactic cosmic rays. We take fully account of the fact that the measurement of the energy of the secondary muons can be used to further discriminate between the signal and the background of atmospheric neutrinos. We conclude that IceCube could identify the sources in the Milagro sky map as the sources of the Galactic cosmic rays at the 3 sigma level in one year and at the 5 sigma level in three years. We discuss the dependence of these expectations on ambiguities, mostly associated with our incomplete knowledge of the astrophysics of the sources.
