Magnetic turbulence production by streaming cosmic rays upstream of SNR shocks
Jacek Niemiec, Martin Pohl
We present preliminary results of Particle-In-Cell simulations of magnetic turbulence production by isotropic cosmic-ray ions streaming upstream of supernova remnant shocks. The st…
The inefficiency of the first-order Fermi process in UHECR production at relativistic shocks
Jacek Niemiec, Michal Ostrowski, Martin Pohl
The question of the origin of ultra-high-energy cosmic rays at relativistic shock waves is discussed in the light of results of recent Monte Carlo studies of the first-order Fermi…
Cosmic ray acceleration at parallel relativistic shocks in the presence of finite-amplitude magnetic field perturbations
Jacek Niemiec, Michal Ostrowski
We study the first-order Fermi acceleration process at parallel shock waves by means of Monte Carlo simulations. A 'realistic' model of the magnetic field turbulence is applied inv…
First-order Fermi Particle Acceleration at Relativistic Shock Waves with a 'Realistic' Magnetic Field Turbulence Model
Jacek Niemiec, Michal Ostrowski
First-order Fermi acceleration process at a relativistic shock wave is investigated by means of Monte Carlo simulations involving numerical integration of particle equations of mot…
