From cosmic ray source to the Galactic pool
K. M. Schure, A. R. Bell
The Galactic cosmic ray spectrum is a remarkably straight power law. Our current understanding is that the dominant sources that accelerate cosmic rays up to the knee ($3 \times 10…
Diffusive shock acceleration and magnetic field amplification
K. M. Schure, A. R. Bell, L. O'C Drury +1
Diffusive shock acceleration is the theory of particle acceleration through multiple shock crossings. In order for this process to proceed at a rate that can be reconciled with obs…
Confining the high-energy cosmic rays
K. M. Schure, A. R. Bell
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 sup…
Cosmic ray acceleration at oblique shocks
A. R. Bell, K. M. Schure, B. Reville
We show that the diffusion approximation breaks down for particle acceleration at oblique shocks with velocities typical of young supernova remnants. Higher order anisotropies flat…
A long-wavelength instability involving the stress tensor
K. M. Schure, A. R. Bell
Cosmic ray acceleration through first-order Fermi acceleration in a collisionless plasma relies on efficient scattering off magnetic field fluctuations. Scattering is most efficien…
A more accurate numerical scheme for diffusive shock acceleration
A. Achterberg, K. M. Schure
We present a more accurate numerical scheme for the calculation of diffusive shock acceleration of cosmic rays using Stochastic Differential Equations. The accuracy of this scheme…
