Electrons and positrons in the galactic cosmic rays
Physical Review D, 1995The detection of primary cosmic ray electrons with energies above 1 TeV implies the existence of a nearby, r\ensuremath{\le}100 pc, and relatively young, t\ensuremath{\le}${10}^{5}$ yr, source(s) of accelerated electrons. Therefore a correct treatment of the formation of the spectra of electrons during their propagation in the interstellar medium ...

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

Galactic Cosmic Rays and the Light Elements
Space Science Reviews, 2001The study of the light elements abundances in low metallicity stars offers a unique way to learn about the past content of our Galaxy in energetic particles (EPs). This study teaches us that either the light elements are not produced by cosmic rays interactions in the interstellar medium (ISM), as has been thought for 30 years, or the cosmic rays are ...

In the early years of the twentieth century, many scientists were baffled by observations of a slow leakage of electric charge from well insulated bodies. With the discovery of the radioactivity of uranium and radium, it was found that while a part of the loss of charge could be due to ionization by radiation from these substances, it was clear that a ...

Propagation of galactic cosmic rays
Astroparticle Physics, 2012Abstract The theoretical aspects of cosmic ray transport in the Galaxy are discussed. The emphasis is on the diffusion model of cosmic ray propagation. The results of the empirical modelling are combined with the approach based on the kinetic theory of particle interaction with random magnetic fields.
