Particle acceleration in thick parallel shocks with high compression ratio
Joni J. P. Virtanen, Rami Vainio
We report studies on first-order Fermi acceleration in parallel modified shock waves with a large scattering center compression ratio expected from turbulence transmission models.…

Stochastic Particle Acceleration in Parallel Relativistic Shocks
Joni J. P. Virtanen, Rami Vainio
We present results of test-particle simulations on both the first- and the second-order Fermi acceleration for relativistic parallel shock waves. Our studies suggest that the role…
