## Summary

, , , , 

The AMS-02 and DAMPE satellites have revolutionized our understanding of high-energy cosmic rays, providing precise measurements of the cosmic ray electron spectrum up to 10 TeV. While the observed spectrum follows a power law distribution without any discernible features above 10 GeV, it is hypothesized that localized sources such as supernova remnants may contribute to electron emissions beyond this threshold. In their work titled "Perspective on the cosmic-ray electron spectrum above TeV," authors Kun Fang, Bing-Bing Wang, Xiao-Jun Bi, Su-Jie Lin, and Peng-Fei Yin delve into this exploration by scrutinizing astrophysical models in light of the latest data from AMS-02 and identifying potential sources for higher energy emissions. With its exceptional energy resolution, DAMPE holds promise for detecting intriguing features in the electron spectrum at energies surpassing TeV levels in forthcoming observations.
