The Galactic positron flux and dark matter substructures
Qiang Yuan, Xiao-Jun Bi
In this paper we calculate the Galactic positron flux from dark matter annihilation in the frame of supersymmetry, taking the enhancement of the flux by existence of dark matter su…
The diffuse Galactic gamma-rays from dark matter annihilation
Xiao-Jun Bi, Juan Zhang, Qiang Yuan +2
The diffuse Galactic -rays from EGRET observation shows excesses above 1 GeV in comparison with the expectations from conventional Galactic cosmic ray (CR) propagation model. In…
Anisotropy and Corotation of Galactic Cosmic Rays
gamma Collaboration, M. Amenomori
The intensity of Galactic cosmic rays is nearly isotropic because of the influence of magnetic fields in the Milky Way. Here, we present two-dimensional high-precision anisotropy m…
Gamma rays from dark matter annihilation in the Draco and observability at ARGO
Xiao-Jun Bi, Hong-Bo Hu, Xinmin Zhang
The CACTUS experiment recently observed a gamma ray excess above 50 GeV from the direction of the Draco dwarf spheroidal galaxy. Considering that Draco is dark matter dominated the…
