We consider a generalized statistical model for the production process of cosmic
rays. This model takes into account temperature distribution of sources and yields
Tsallis statistics for cosmic ray energy spectrum. Results are compared with the
experimental data.

Gamma rays have long been recognized as a uniquely powerful probe of the existence, origin, and nature of cosmic
rays beyond the solar system. The unprecedented sensitivity and resolution of GLAST should for the first time
confirm the presence of cosmic rays in Local Group galaxies today, and in all galaxies throughout the history of
cosmic star formation. We show that GLAST should detect,

Based on the cosmic-ray (CR) data currently available, we estimate the gas
density, diffusion coefficient, and their spacial gradient in both the longitudinal
and the latitudinal directions in the Galaxy. Applying our model on the three
dimensional CR propagation for various CR observables such as stable nuclear
components, isotopes, antiprotons, diffuse gamma-rays, we present analytical

We report on a project to constrain the large-scale and turbulent magnetic fields of
the Milky Way galaxy, which eventually will incorporate all of the relevant
observational data. The initial work is based primarily on the WMAP3 polarization
and intensity maps, plus a large number of galactic and extragalact point source
Faraday Rotation Measures. Preliminary results on the Galactic magneti

We present a Monte-Carlo calculation of the propagation of cosmic ray protons in the
Galaxy for energies above 1 PeV. We discuss the relative strengths of competing
effects such as parallel/perpendicular diffusion and drifts in toy models of the
Galaxy. We compare our estimates with the results of the MC calculation for the toy
models and then we apply the MC calculation to a few realistic mod

The long-duration balloon flights of TRACER have provided new measurements of the
intensities and energy spectra of the arriving cosmic-ray nuclei with 5 ≤ Z ≤ 26 at
high energies. In order to determine the particle composition and energy spectra at
the cosmic-ray sources, changes occurring during the interstellar propagation of
cosmic rays must be known. We use a simple propagation mode

Diffuse VHE γ radiation from the Galactic center ridge observed by the H.E.S.S.
telescope has been convincingly linked with the propagation of recently accelerated
cosmic rays that interact with molecular hydrogen clouds during their diffusion.
Through a series of time-dependent simulations of that diffusion for different
propagation parameters we have obtained the most probable values of the
