Cosmic rays (CRs) are an integral component of the interstellar medium, producing broadband emission while interacting with other Galactic matter components like gas or magnetic fields. In addition to observations, numerical simulations CR propagation through Galaxy help increase level understanding transport and diffuse γ-ray as seen by different experiments. Up now, standard approach at model...

We have made a new calculation of the cosmic-ray secondary positron spectrum using a diffusive halo model for Galactic cosmic-ray propagation. The code computes self-consistently the spectra of primary and secondary nucleons, primary electrons, and secondary positrons and electrons. The models are first adjusted to agree with the observed cosmic-ray Boron/Carbon ratio, and the interstellar prot...
