چکیده

The probability that a particle, crossing the shock along a given direction, be reflected backwards along another direction, was shown to be the key element in determining the spectrum of non–thermal particles accelerated via Fermi mechanism around a shock. Here an explicit equation for this probability distribution is given, for both the upstream and downstream sections. Though analytically intractable, this equation can be easily solved numerically. Subject headings: shock waves – cosmic rays

On particle acceleration around shocks. I

We derive a relativistically covariant (although not manifestly so) equation for the distribution function of particles accelerated at shocks, which applies also to extremely relativistic shocks, and arbitrarily anisotropic particle distributions. The theory is formulated for arbitrary pitch angle scattering, and reduces to the well–known case for small angle scatterings via a Fokker–Planck app...

On particle acceleration around shocks II: a fully general method for arbitrary shock velocities and scattering media

The probability that a particle, crossing the shock along a given direction, be reflected backwards along another direction, was shown to be the key element in determining the spectrum of non–thermal particles accelerated via the Fermi mechanism around a plane–parallel shock in the test–particle limit. Here an explicit equation for this probability distribution is given, for both the upstream a...

Anomalous transport and particle acceleration at shocks

The theory of first order Fermi acceleration at shocks assumes that particles diffuse due to scattering off slow-moving magnetic irregularities. However, cosmic rays are closely tied to magnetic field lines, and the transport process, particularly across the direction of the field, is likely to be more complicated. To describe cross field transport we employ recent extensions of the Rechester-R...

Ultra high energy cosmic rays: subluminal and superluminal shocks

Diffusive shock acceleration is invoked to explain non-thermal particle acceleration in Supernova Remnants, Active Galactic Nuclei (AGN) Jets, Gamma ray Bursts (GRBs) and various large scale cosmic structures. The importance of achieving the highest observed particle energies by such a mechanism in a given astrophysical situation is a recurring theme. In this work, shock acceleration in relativ...
