International School of Cosmic Ray Astrophysics
15th Course: "Astrophysics at Ultra-High Energies"
20-27 June 2006
Ettore Majorana Centre
Erice, Sicily, Italy
Topic: Transport of High Energy Particles in the Galaxy and Beyond
Lecturer: Vladimir Ptuskin
The propagation of cosmic rays in the interstellar medium and the
intergalactic space is discussed. It is shown how parameters of propagation
model can be obtained from the data on cosmic energy spectrum, composition, and
anisotropy. This empirical approach is supported by the kinetic theory of
relativistic particle motion in cosmic magnetic fields.
