Abstract
Recently, an excess of GeV gamma ray near the Galactic Centre has beenvreported. The spectrum obtained can be best fitted with the annihilationvof GeV dark matter particles through channel. In this letter, I show that this annihilation model can also solve the mysteries of heating source in x-ray plasma and the unexpected high gamma-ray luminosity. The cross section constrained by these observations give excellent agreements with both the predicted range by using Fermi-LAT data and the canonical thermal relic abundance cross section.
