Many X-ray and non-thermal emissions are observed in the Galaxy. It is, however, unknown what is the origin of hot(˜ 7 keV) diffuse X-ray gas such as Galactic ridge X-ray emission, including non-thermal component. Tanuma et al.(1999) suggested that the X-ray gas are created by magnetic reconnection which occurs in the locally strong(˜ 30 µG) interstellar magnetic field in the Galaxy. In this paper, we suggest that the non-thermal emission from high energy particles are also created by the reconnection, and examine this model by performing two-dimensional numerical resistive magnetohydro dynamic simulations. As the results, we find that the fast reconnection starts immediately after the plasmoid ejection, which are created by the secondary tearing instability. The internal shocks are created in the reconnection jet due to the non-steady plasmoid-ejection. In the next phase, the reconnection jet oscillates due to KelvinHelmholtz instability, so that the multiple fast (oblique) shocks are created. The magnetic reconnection and fast shocks are possible mechanism to generate the diffuse X-ray gas and high energy particles in the Galaxy.
