Cosmic electrons, galactic radio background and cosmic ray confinement
Cosmic ray electron measurements and radio background data are analyzed to obtain bounds on the galactic magnetic fields. It is shown that the magnetic field required to explain the radio flux must be greater than 2 micro Gauss. The difference in the steepening of the radio spectra towards the Anticenter and the Halo Minimum provides evidence that the magnetic field decreases with the height above the galactic plane. The calculations of Bulanov and Dogiel (1975) are applied to the radio and electron observations. It is shown that the most plausible interpretation of these results requires that the electron injection spectrum has an intrinsic flattening below a few GeV. The observed steepening of radio and electron data is apparently a combined effect of the injection spectrum and the first break due to continuous energy loss of electrons in space.
