Cosmic ray spectra and anisotropy under anisotropic propagation model with spiral galactic sources
Aifeng Li, Zhaodong Lv, Wei Liu +2
In our previous work, we have investigated Galactic cosmic ray (GCR) spectra and anisotropy from 100 GeV to PeV, under anisotropic propagation model with axisymmetric distributed g…

X-ray Binaries: a potential dominant contributor to the cosmic ray spectral knee structure
Hua Yue, Jianli Zhang, Yuhai Ge +5
``PeVatrons" refer to astrophysical sources capable of accelerating particles to energies PeV and higher, potentially contributing to the cosmic ray spectrum in the knee regi…

Geminga: A Window into the Role Played by the Local Halo in the Cosmic-Ray Propagation Process
Lin Nie, Yu-Hai Ge, Yi-Qing Guo +1
A novel phenomenon among the recently observed Geminga pulsar halo is the presence of distinct radiation morphology at high energies, while no extended radiation is detected in the…
