论文摘要
银河宇宙射线(CRS)的组成和光谱对于在各种环境和不同尺度上的高能过程的研究,对伽马射线和微波观测的解释,解散新现象的可能标志以及对我们当地的银河系社区的理解。自推出以来,AMS-02已经对抗蛋白质,电子,正上音和核的光谱进行了出色的质量测量:H-O,NE,NE,MG,SI。这些测量结果导致了许多突破,但是,直到任务后期,才期望较重的核,尤其是尤其是低增强核的光谱。同时,将已发布的AMS-02结果与来自Heo-3-C2的早期数据进行比较表明,Heao-3-C2数据可能受到无证件系统错误的影响。利用此类数据来补偿缺乏AMS-02测量结果可能导致重大错误。在本文中,我们表明,Heao-3-C2数据的一部分匹配可用的AMS-02测量值非常好,并且可以与Voyager 1和Ace-Cris数据一起使用,以预测AMS-02尚未发布的核的局部星际光谱(LIS)。我们还正在更新已经发布的LIS,以提供从1 MeV/核的H-NI的完整集合,从1 MeV/核能到〜100-500 TEV/核,从而覆盖了8-9个数量级的能量级。我们的计算采用了Galprop-Helmod框架,该框架被证明是推导Cr抗抗脂子,电子和核H-O的可靠工具。
Composition and spectra of Galactic cosmic rays (CRs) are vital for studies of high-energy processes in a variety of environments and on different scales, for interpretation of gamma-ray and microwave observations, disentangling possible signatures of new phenomena, and for understanding of our local Galactic neighborhood. Since its launch, AMS-02 has delivered outstanding quality measurements of the spectra of antiprotons, electrons, positrons, and nuclei: H-O, Ne, Mg, Si. These measurements resulted in a number of breakthroughs, however, spectra of heavier nuclei and especially low-abundance nuclei are not expected until later in the mission. Meanwhile, a comparison of published AMS-02 results with earlier data from HEAO-3-C2 indicate that HEAO-3-C2 data may be affected by undocumented systematic errors. Utilizing such data to compensate for the lack of AMS-02 measurements could result in significant errors. In this paper we show that a fraction of HEAO-3-C2 data match available AMS-02 measurements quite well and can be used together with Voyager 1 and ACE-CRIS data to make predictions for the local interstellar spectra (LIS) of nuclei that are not yet released by AMS-02. We are also updating our already published LIS to provide a complete set from H-Ni in the energy range from 1 MeV/nucleon to ~100-500 TeV/nucleon thus covering 8-9 orders of magnitude in energy. Our calculations employ the GalProp-HelMod framework that is proved to be a reliable tool in deriving the LIS of CR antiprotons, electrons, and nuclei H-O.
