Several groups have reported a possible excess of primary electrons at high energies with the joint fit of the positron fraction and total electron/positron spectra. With the latest release of high-precision electron/positron spectra measured by AMS-02, we further confirm this excess by fitting ∆Φ (i.e.,Φe− − Φe+) data in this work. Then we investigate the contribution of a single nearby supernova remnant to the primary electron excess and find that Monogem can reasonably account for this…

Statistically study the optimal local sources for cosmic ray nuclei and electron
The local sources, such as Geminga SNR, may play important role for the anomaly of proton, electron and anisotropy in the past works. In fact, there exists twelve SNRs around solar system within 1


Origin of Cosmic Rays
The observed isotropy of the cosmic rays incident on the earth is claimed to be a consequence of a magnetic field assumed to exist in interstellar space, which is compared with the average interstellar field of 10−20 gauss.
Cosmic rays and particle physics
The study of high energy cosmic rays is a diversified field of observational and phenomenological physics addressing questions ranging from shock acceleration of charged particles in various
