Transformation of the Poynting flux into kinetic energy in relativistic jets
Transformation of the Poynting flux into kinetic energy in relativistic jets
The acceleration of relativistic jets from the Poynting- to the matter-dominated stage is considered. There are generally two collimation regimes, which we call equilibrium and non-equilibrium respectively. In the first regime, the jet is efficiently accelerated up to the equipartition between the kinetic and electromagnetic energy. We show that after …
