Dust-driven streaming instability and magnetic field amplification downstream of supernova remnant shocks
S. Gabici, J. C. Raymond, A. Ciardi +3
The acceleration of cosmic rays up to PeV energies at supernova remnant shocks requires an amplification of the ambient magnetic field. The amplification mechanism must operate ups…

Efficient ion re-acceleration in laboratory-produced interpenetrating collisionless shocks
W. Yao, I. Cohen, P. Suarez Gerona +20
Although the origin of cosmic rays (CRs) remains an open question, collisionless magnetized shock waves are widely regarded as key sites for particle acceleration. Recent theories…

Interplay between the non-resonant streaming instability and self-generated pressure anisotropies
Alexis Marret, Andrea Ciardi, Roch Smets
The non-thermal particles escaping from collisionless shocks into the surrounding medium can trigger a non-resonant streaming instability that converts parts of their drift kinetic…
