Magnetized Current Filaments as a Source of Circularly Polarized Light
U. Sinha, J. Martins, J. Vieira +3
We show that the Weibel or currente filamentation instability can lead to the emission of circularly polarized radiation. Using particle-in-cell (PIC) simulations and a radiation p…
Bright gamma-ray flares powered by magnetic reconnection in QED-strength magnetic fields
K. M. Schoeffler, T. Grismayer, D. Uzdensky +2
Strong magnetic fields in magnetospheres of neutron stars (especially magnetars) and other astrophysical objects may release their energy in violent, intense episodes of magnetic r…
Physics of collisionless shocks - theory and simulation
A. Stockem Novo, A. Bret, R. A. Fonseca +1
Collisionless shocks occur in various fields of physics. In the context of space and astrophysics they have been investigated for many decades. However, a thorough understanding of…
Slow down of a globally neutral relativistic beam shearing the vacuum
E. P. Alves, T. Grismayer, M. G. Silveirinha +2
The microphysics of relativistic collisionless sheared flows is investigated in a configuration consisting of a globally neutral, relativistic beam streaming through a hol…
Electromagnetic field generation in the downstream of electrostatic shocks due to electron trapping
A. Stockem, T. Grismayer, R. A. Fonseca +1
A new magnetic field generation mechanism in electrostatic shocks is found, which can produce fields with magnetic energy density as high as 0.01 of the kinetic energy density of t…
Electron trapping and acceleration by the plasma wakefield of a self-modulating proton beam
K. V. Lotov, A. P. Sosedkin, A. V. Petrenko +6
It is shown that co-linear injection of electrons or positrons into the wakefield of the self-modulating particle beam is possible and ensures high energy gain. The witness beam mu…
