Collision of two radial rarefaction waves in unmagnetized ambient plasma: effects of the ambient plasma density
Margaux François, Mark E. Dieckmann, Lorenzo Romagnani +2
The expansion of two circular rarefaction waves in vacuum or in a thin ambient plasma is examined with particle-in-cell simulations that resolve two spatial dimensions. In the simu…

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…
