Recently AMS-02 collaboration publish their measurements of light cosmic-ray nuclei, including lithium, beryllium, boron, carbon and oxygen. All of them reveal a prominent excess above $\sim$ 200 GV, coinciding with proton and helium. Particularly, the secondary cosmic rays even harden than the primary components above that break. One of the viable interpretations for above anomalies is the spatial-dependent diffusion process. Such model has been successfully applied to multiple observational phenomena, for example primary cosmic ray nuclei, diffuse gamma ray and anisotropy. In this work, we investigate the spatial-dependent propagation model in light of the new observational data. We find that such model is able to explain the upturn of secondary spectrum as well as the primary's. All the spectra can be well reproduced and the calculated ratios are also in good agreement with the observations.
Revisiting the complex nuclear region of NGC 6240 with Chandra
我们提出了一个重新分析的累积ACIS S钱德拉数据集指向的双活动星系的NGC 6240合并星系，集中在硬能带包含硬光谱连续（5.5-5.9 keV），红移Fe I K α线（6.0-6.4 keV），和红移Fe XXV线（6.4-6.7 keV）。我们充分利用了Chandra望远镜的角分辨率，并通过比较飞行前的定标模型和两个明亮活动星系核的数据来模拟Chandra PSF。有两种互补的方法：（1）研究PSF相减后的残差，（2）通过马尔可夫链蒙特卡罗（EMC 2）图像产生重建的期望，我们能够分辨SAGN中从1 kpc到<200 pc的结构。后者在波黑的势力范围内。我们发现，在连续谱和Fe线显着的扩展发射在2“（1千秒差距）的区域周围的核，在该地区之间的N和S AGN，并在一个部门的PA 120-210度。从南活动星系核表面亮度的质心向东南方向延伸。扩展的Fe I K α发射可能源于X射线光子与致密分子云相互作用的荧光，为最近的高分辨率ALMA研究提供了补充观点。非热辐射在两个活跃的X射线核之间的区域和NAGN中更为普遍。我们没有发现与最近提出的NGC 6240的第三个核有关的X射线发射的有力证据。
