A mechanism that could stop the acceleration process within a collisionless shock
Antoine Bret, Asaf Pe'er
Collisionless shocks are complex nonlinear structures that are not yet fully understood. In particular, the interaction between these shocks and the particles they accelerate remai…

On the width of a collisionless shock and the index of the cosmic rays it accelerates
Antoine Bret, Asaf Pe'er
Despite being studied for many years, the structure of collisionless shocks is still not fully determined. Such shocks are known to be accelerators of cosmic rays, which, in turn,…

Density jump for oblique collisionless shocks in pair plasmas: physical solutions
Antoine Bret, Colby C. Haggerty, Ramesh Narayan
Collisionless shocks are frequently analyzed using the magnetohydrodynamics (MHD) formalism, even though MHD assumes a small mean free path. Yet, isotropy of pressure, fruit of bin…
