膝关节在Cosmic-Ray能量谱中的起源

The Origin of the Knee in the Cosmic-Ray Energy Spectrum

A. D. Erlykin, A. W. Wolfendale

摘要:

在能量约为3 PeV(1 PeV = 10 $^{15}$ eV)时,观测到宇宙射线能谱(拐点)突然变陡。最近关于广泛的空气簇射的结果使我们能够得出以下结论:a)膝关节具有天体物理学的起源; b)膝关节的“锐度”和精细结构排除了“银河调制”作为膝关节的起源; c)膝关节很可能是最近附近一颗超新星爆炸的结果。

英文摘要:

A sudden steepening of the cosmic-ray energy spectrum (the knee) is observed at an energy of about 3 PeV (1 PeV = 10$^{15}$eV). The recent results on extensive air showers allow us to conclude that: a) the knee has an astrophysical origin; b) the 'sharpness' and the fine structure of the knee rule out 'Galactic Modulation' as the origin of the knee; c) most likely the knee is the result of the explosion of a single, recent, nearby supernova.
