Abstract | Astrophysical jets are composed of plasmas in which there are relativistic electrons and other cosmic ray particles generated by in situ reacceleration. The equilibrium analysis of a non-neutral beam-plasma system shows that the fluid components rotate around the cylindrical axis. When the relativistic electrons propagate through the background plasma of astrophysical jets, it is found that even very small non-neutrality will cause a differential rotation velocity large enough to amplify magnetic fields to a few microgausses on kiloparsec scales by the kinematic screw dynamo mechanism. The amplified magnetic field concentrates within a thin cylindrical shell, so it is beneficial for the confinement and collimation of jets |
