Collisionless shock formation, spontaneous electromagnetic fluctuations and streaming instabilities

A. Bret, A. Stockem, F. Fiuza +4

Collisionless shocks are ubiquitous in astrophysics and in the lab. Recent numerical simulations and experiments have shown how they can arise from the encounter of two collisionle…

The impact of kinetic effects on the properties of relativistic electron-positron shocks

A. Stockem, F. Fiuza, R. A. Fonseca +1

We assess the impact of non-thermally shock-accelerated particles on the magnetohydrodynamic (MHD) jump conditions of relativistic shocks. The adiabatic constant is calculated dire…

Large-scale magnetic field generation via the kinetic Kelvin-Helmholtz instability in unmagnetized scenarios

E. P. Alves, T. Grismayer, S. F. Martins +3

Collisionless plasma instabilities are fundamental in magnetic field generation in astrophysical scenarios, but their role has been addressed in scenarios where velocity shear is a…

The nonlinear saturation of the non-resonant kinetically driven streaming instability

L. Gargate, R. A. Fonseca, J. Niemiec +3

A non-resonant instability for the amplification of the interstellar magnetic field in young Supernova Remnant (SNR) shocks was predicted by Bell (2004), and is thought to be relev…

Ion dynamics and acceleration in relativistic shocks

S. F. Martins, R. A. Fonseca, L. O. Silva +1

Ab-initio numerical study of collisionless shocks in electron-ion unmagnetized plasmas is performed with fully relativistic particle in cell simulations. The main properties of the…
