Streaming instabilities are thought to play a fundamental role in both
the processes of acceleration and propagation of Cosmic Rays in the
Galaxy.
Resonant scattering on self-generated magnetic turbulence has long
been recognized as the most plausible mechanism for the confinemet of
energetic particles. The streaming of these particles along magnetic
field lines at super-alfvenic...

Diffusive shock acceleration is the prime candidate for efficient acceleration of cosmic rays. Galactic cosmic rays are believed to originate predominantly from this process in supernova remnant shock waves. Confinement of the cosmic rays in the shock region is key in making the mechanism effective. It has been known that on small scales (smaller than the typical gyroradius) high-amplitude...

We calculate the flux of non-thermal radiation from the Tycho's supernova remnant in the context of the non-linear theory of particle acceleration at shocks, which allows us to take into account self-consistently the dynamical reaction of the accelerated particles, the generation of magnetic fields in the shock proximity and the dynamical reaction of the magnetic field on the plasma....

It is known that two shocks co-exist in young Supernova Remnants (SNRs) during their free expansion into the circumstellar/interstellar medium. It is widely accepted that the forward shock is responsible for the bulk of accelerated particles and the creation of a non-thermal power-law distribution of cosmic-rays. Under a test-particle approach the index of the power-law spectrum at high...

The advent of high sensitivity, high resolution gamma-ray detectors,
together with a knowledge of the distribution of the atomic hydrogen and
especially of the molecular hydrogen in the Galaxy on sub-degree scales
creates a unique opportunity to explore the flux of cosmic rays in the
Galaxy. We here present a methodology which aims to provide a test bed for
current and future gamma-ray...
