Big bang nucleosynthesis constrains the total annihilation cross section of neutralino dark matter
Xiao-Jun Bi
Assuming the lightest neutralino forms dark matter, we study its residual annihilation after freeze-out at the early universe. If taking place after the big bang nucleosynthesis (B…
Diffuse -rays and flux from dark matter annihilation -- a model for consistent results with EGRET and cosmic ray data
Xiao-Jun Bi, Juan Zhang, Qiang Yuan
In this work we develop a new propagation model for the Galactic cosmic rays based on the GALPROP code, including contributions from dark matter annihilation. The model predicts co…
Future plan for observation of cosmic gamma rays in the 100 TeV energy region with the Tibet air shower array : physics goal and overview
M. Amenomori, X. J. Bi, D. Chen +82
The Tibet air shower array, which has an effective area of 37,000 square meters and is located at 4300 m in altitude, has been observing air showers induced by cosmic rays with ene…

Mapping the dark trajectory of the Bullet Cluster
Xiao-Jun Bi, HongSheng Zhao
We model the electrons/positrons produced by dark matter annihilations in the colliding galaxy cluster system 1E0657-56 (the bullet cluster). These charged particles, confined by t…
Constraining supersymmetry from the satellite experiments
Xiao-Jun Bi
In this paper we study the detectability of -rays from dark matter annihilation in the subhalos of the Milky Way by the satellite-based experiments, EGRET and GLAST. We work in…
