Cocoon formation by a mildly relativistic pair jet in unmagnetized collisionless electron-proton plasma
M E Dieckmann, G Sarri, D Folini +2
By modelling the expansion of a cloud of electrons and positrons with the temperature 400 keV that propagates at the mean speed 0.9c ( speed of light) through an initially unma…
Expansion of a mildly relativistic hot pair cloud into an electron-proton plasma
ME Dieckmann, A Alejo, G Sarri
The expansion of a charge-neutral cloud of electrons and positrons with the temperature 1 MeV into an unmagnetized ambient plasma is examined with a 2D particle-in-cell (PIC) simul…
A thin-shell instability in collisionless plasma
M. E. Dieckmann, H. Ahmed, D. Doria +6
The thin-shell instability has been named as one process, which can generate entangled structures in astrophysical plasma on collisional (fluid) scales. It is driven by a spatially…
Shocks in unmagnetized plasma with a shear flow: Stability and magnetic field generation
M. E. Dieckmann, A. Bock, H. Ahmed +4
A pair of curved shocks in a collisionless plasma is examined with a two-dimensional particle-in-cell (PIC) simulation. The shocks are created by the collision of two electron-ion…
PIC simulation study of the interaction between a relativistically moving leptonic micro-cloud and ambient electrons
M. E. Dieckmann, G. Sarri, S. Markoff +2
The jets of compact accreting objects are composed of electrons and a mixture of positrons and ions. These outflows impinge on the interstellar or intergalactic medium and both pla…
The evolution of a slow electrostatic shock into a plasma shock mediated by electrostatic turbulence
Mark Eric Dieckmann, Gianluca Sarri, Domenico Doria +2
The collision of two plasma clouds at a speed that exceeds the ion acoustic speed can result in the formation of shocks. This phenomenon is observed not only in astrophysical scena…
Time-resolved characterization of the formation of a collisionless shock
H Ahmed, ME Dieckmann, L Romagnani +11
We report on the temporally and spatially resolved detection of the precursory stages that lead to the formation of an unmagnetized, supercritical collision-less shock in a laser-d…
PIC simulation of a thermal anisotropy-driven Weibel instability in a circular rarefaction wave
M. E. Dieckmann, G. Sarri, G. C. Murphy +6
The expansion of an initially unmagnetized planar rarefaction wave has recently been shown to trigger a thermal anisotropy-driven Weibel instability (TAWI), which can generate magn…
