Abstract:

When astrophysical jets interact with the ambient medium through which they propagate, they lose energy and entrain and accelerate that medium. Recent observations of such interactions, including time-lapsed movies of both AGN and microquasar jets, can be used to inform models of the jet-ambient-medium interactions. In this paper, we discuss some aspects of these jets, including the mechanisms of their propagation, their constitution and the non-linear character of their energy loss via plasma processes. We also present for the first time PIC code simulations to show momentum transfer via caviton formation as a result of plasma processes. An illustration of the microphysics of the interaction of a proton-electron beam with an ambient magnetic field is also presented.
