| 英文摘要 | Abstract the ams-02 has measured the cosmic-ray electron (plus positron) spectrum up to ～tev with unprecedented precision. the spectrum can be well described by a power law without any obvious features above 10 gev. the satellite instrument dark matter particle explorer (dampe), which was launched a year ago, will measure the electron spectrum up to 10 tev with high-energy resolution. the cosmic electrons beyond tev may be attributed to few local cosmic-ray sources, such as supernova remnants. therefore, spectral features, such as cut-off and bumps, can be expected at high energies. in this work, we provide a careful study on the perspective of the electron spectrum beyond tev. we first examine our astrophysical source models on the latest leptonic data of ams-02 to give a self-consistent picture. then we focus on the discussion about the candidate sources, which could be electron contributors above tev. depending on the properties of the local sources (especially on the nature of vela), dampe may detect interesting features in the electron spectrum above tev in the future. |
