Radio Radiation Mechanism of Two-Streams Plasma in the Astrophysical Jet

Abstract

To explain the radio mechanism of non-relativistic jets, we investigate a nonlinear process in which ion-acoustic waves scatter into high frequency electromagnetic waves by the plasma having a non-Maxwell distribution with non-relativisical energetic electrons. The calculated reaults show that this mechanism is efficient, and may apply to the radiation of jets from active galaxies and radio bursts of sun flares.
