We present new-generation mechanisms of magnetic fields in supernova remnant shocks propagating to partially ionized plasmas in the early universe. Upstream plasmas are dissipated at the collisionless shock, but hydrogen atoms are not dissipated because they do not interact with electromagnetic fields. After the hydrogen atoms are ionized in the shock downstream region, they become cold proton beams that induce the electron return current. The injection of the beam protons can be interpreted as… Expand

A new generation mechanism of the magnetic field in an inhomogeneous collisionless plasma with a beam component is proposed. We show that even though the current and charge neutralities are initiallyExpand
Weibel-mediated Shocks Propagating into Inhomogeneous Electron–Positron Plasmas
The external forward shock emitting the gamma-ray burst (GRB) afterglow is collisionless, and it is mediated by the Weibel instability which generates the magnetic field. The GRB afterglow shows thatExpand
Turbulent dynamo in a collisionless plasma
TLDR
It is shown that magnetic field amplification by dynamo instability does occur in a stochastically driven, nonrelativistic subsonic flow of initially unmagnetized collisionless plasma and that the dynamo self-accelerates and becomes entangled with kinetic instabilities as magnetization increases.

Self‐generation of magnetic fields by sheared flows in weakly ionized plasmas
A sheared, relative ion–neutral flow can generate a magnetic field in an unmagnetized, weakly ionized plasma. The field generation term is ∂B/∂t=(mec/e)∇×νen(Vi−Vn) where νen is the electron–neutralExpand
Biermann Mechanism in Primordial Supernova Remnant and Seed Magnetic Fields
We study the generation of magnetic fields by the Biermann mechanism in the supernova explosions of the first stars. The Biermann mechanism produces magnetic fields in the shocked region between theExpand
Generation of the Primordial Magnetic Fields during Cosmological Reionization
We investigate the generation of magnetic fields by the Biermann battery in cosmological ionization fronts, using new simulations of the reionization of the universe by stars in protogalaxies. TwoExpand
Spatial Structure and Collisionless Electron Heating in Balmer-dominated Shocks
Balmer-dominated shocks in supernova remnants (SNRs) produce strong hydrogen lines with a two-component profile composed of a narrow contribution from cold upstream hydrogen atoms and abroadExpand
Non-Maxwellian Proton Velocity Distributions in Nonradiative Shocks
The Balmer line profiles of nonradiative supernova remnant shocks provide the means to measure the postshock proton velocity distribution. While most analyses assume a Maxwellian velocityExpand

The interest in relativistic beam-plasma instabilities has been greatly rejuvenated over the past two decades by novel concepts in laboratory and space plasmas. Recent advances in this long-standingExpand
