Galactic cosmic rays & gamma rays: a synthesis
Abstract
We have developed a model which aims to reproduce observational data of many kinds related to cosmic-ray origin and propagation: direct measurements of nuclei, antiprotons, electrons and positrons, gamma-rays, and synchrotron radiation. Our main results include evaluation of diffusion/convection and reacceleration models, estimates of the halo size, calculations of the interstellar positron and antiproton spectra, evaluation of alternative hypotheses of nucleon and electron interstellar spectra, and computation of the Galactic diffuse gamma-ray emission. We show that combining information from classical cosmic-ray studies with gamma-ray and other data leads to tighter constraints on cosmic-ray origin and propagation.
