  ABSTRACT: Cosmic ray (CR) nuclei are accelerated particles which move randomly through the interstellar medium (ISM), where they suffer scattering, reacceleration and energy loss processes before reaching Earth. Spallation processes also take place forming secondary nuclei by fragmentation of heavier ones. Due to the impossibility of observing directly their original direction, the determination of possible sources where these particles originated requires the use of codes to simulate the propagation of CR within the Galaxy. This consists of a spiral disk with a thickness of 2h ~ 200 pc, where CR are created, and a halo with a height H, where they diffuse.

  ABSTRACT: In this note, we report the results of a simulation of the galactic component of high energy gamma rays, as seen by the future AMS-02 experiment on-board the International Space Station. The purpose of AMS is to measure the Cosmic Ray spectra of numerous particles with unprecedented accuracy. This simulation has been performed with the GALPROP code and its output interfaced with the AMS Fast Simulator, to produce a sky-map of yearly counts in the AMS energy range (over 1 GeV).

  ABSTRACT: We will analyze the importance of varying the diffuse gas radial distribution on the resulting expected cosmic rays spectrum. We use the recent HI density data published by Nakanishi et al. (2004), and include them in the cosmic rays propagation code GALPROP (Strong & Moskalenko 1998). We will obtain those models that reproduce the characteristics shown by the cosmic rays data, and we will then extract information about the Galaxy structure.
