Spectra of protons and electrons. Left: preexisting ambient CR spectra of protons (solid black) and electrons (dashed red) from Phan et al. (2018) as a function of the kinetic energy of the particles. Right: reaccelerated and compressed protons (solid black) and electrons (dashed red) vs kinetic energy with radiative compression s = 12, a cutoff at 100 GeV, and a break at 50 GeV as reference values.
