The Astrophysics of Galactic Cosmic Rays
Space Science Reviews, 2001Observations of cosmic rays and their related radio to gamma-ray signatures are surveyed and discussed critically, and compared to theoretical models of the cosmic-ray origin and propagation. The analogous heliospheric processes are included as a well-studied case of the principal physical processes of energetic particle acceleration and propagation ...

We have shown in Chap. 16 that the acceleration of galactic cosmic rays below a few 1015 eV/nucl. with power law momentum spectra can be well explained by diffusive shock wave acceleration near galactic supernova remnants, which also, by the overall power requirements (see Chap. 7), are the most probable sources of galactic cosmic rays. Here we address

Journal of Physics G: Nuclear and Particle Physics, 1998
The arrival direction distribution of the highest-energy cosmic rays with respect to Galactic latitude has been analysed using both the Yakutsk and the available world data from extensive air shower arrays. A north-south asymmetry is indicated in the distribution observed with the Yakutsk array at in the outer Galaxy direction.

Galactic cosmic rays and nucleosynthesis
AIP Conference Proceedings, 2010The nucleosynthesis of the light elements Li, Be and B by galactic cosmic rays is presented. Observations of cosmic rays and the nuclear reactions responsible for Li, Be and B nucleosynthesis are described, followed by some words on propagation. At the end, some open questions concerning galactic cosmic rays are discussed.

Cosmic-ray-driven galactic wind
Il Nuovo Cimento B Series 11, 1991A simple one-dimensional Cartesian solution of the magnetohydrodynamic equations describing the global motion of interstellar matter including the effects of cosmic-ray and magnetic-field pressure is presented. First an adiabatic equation of state for the thermal background plasma and a loss-free cosmic-ray gas in the strong-scattering limit is ...

Origin of Galactic Cosmic Rays
AIP Conference Proceedings, 2005The problem of cosmic ray origin is briefly discussed. The discussion covers the acceleration in supernova remnants, the diffusion model of cosmic ray propagation in the Galaxy, the nature of “knee” in cosmic ray spectrum, and the connection to gamma‐ray astronomy.

Acceleration of galactic cosmic rays
La Rivista del Nuovo Cimento, 2019More than a century ago it was discovered that the Earth is bombarded by a penetrating radiation of cosmic origin, whose flux was later found to be dominated by charged particles. The discovery of cosmic rays led to many questions about their origin and about the way that they reach us from large distances.

Galactic Propagation of Cosmic Rays
1983After introducing various phenomenological models of cosmic ray propagation in the galaxy, we examine how some of thera fare when compared to the data. We show that a model based on resonant diffusion of cosmic rays off an interstellar spectrum of hydromagnetic waves can account for the presently available evidence on cosmic rays and the interstellar ...
