| Abstract: | We present computer simulation studies of the magnetic field generation by colliding electron clouds in cosmic plasmas. Simulation results exhibit purely growing magnetic fields, generation of electrostatic waves and subsequent electron energization in different regimes. The linear growth and saturated magnetic fields in our simulations are in good agreement with recent theoretical predictions of the Weibel instability induced magnetic fields in cosmological plasmas. |
