Ionization Rates Due to Cosmic-Rays Throughout our Galaxy

Go to: IG Ionization Rate

The ionization rate due to cosmic rays is shown as a function of radial R and vertical Z position in the diffusive cosmic ray halo that encompasses our Galaxy. The flux of the various cosmic-ray species from which these results have been derived comes from the detailed numerical diffusion model described by Strong & Moskalenko (1998). In this model, the Galaxy is assumed to be axisymmetric and the surface of the diffusive cosmic-ray halo is located at 4 kpc above and below the midplane of the Galaxy's disk.
