空气簇射测量的Cosmic Ray能谱

Cosmic Ray Energy Spectrum from Measurements of Air Showers

Thomas K. Gaisser, Todor Stanev, Serap Tilav

摘要:

这篇评论集中在高能宇宙射线在PeV能量范围和以上。特别令人感兴趣的是3 PeV附近的光谱拐点和从银河系起源的宇宙射线到河外来源的粒子的过渡。我们的目标是通过结合不同能量下的许多测量结果,建立一个从10^14到10^20 eV的基线光谱。结合测量的核组成的原色,能谱的形状的地方限制的数量和频谱的来源,可能有助于观察到的频谱。

英文摘要:

This review focuses on high-energy cosmic rays in the PeV energy range and above. Of particular interest is the knee of the spectrum around 3 PeV and the transition from cosmic rays of Galactic origin to particles from extra-galactic sources. Our goal is to establish a baseline spectrum from 10^14 to 10^20 eV by combining the results of many measurements at different energies. In combination with measurements of the nuclear composition of the primaries, the shape of the energy spectrum places constraints on the number and spectra of sources that may contribute to the observed spectrum.
