Abstract:
Measurements of cosmic ray directional properties at about eV in both northern and southern hemispheres confirm that those particles have a unidirectional anisotropy and are flowing along the direction of our spiral arm from the inner galactic regions. On the basis of diffusive cosmic ray flow along the galactic arms, the power required for the galaxy to maintain this flow is below watts.
