Magnetic field generation in relativistic shocks - An early end of the exponential Weibel instability in electron-proton plasmas
J. Wiersma, A. Achterberg
We discuss magnetic field generation by the proton Weibel instability in relativistic shocks, a situation that applies to the external shocks in the fireball model for Gamma-ray Bu…

Magnetic field generation in relativistic shocks
Jorrit Wiersma, A. Achterberg
We present an analytical estimate for the magnetic field strength generated by the Weibel instability in ultra-relativistic shocks in a hydrogen plasma. We find that the Weibel ins…
