Outflows are ubiquitous phenomena in the universe. They have been widely observed in both Galactic and extragalactic objects. In this thesis, we analyze three individual sources. We utilize for the first time the Planck observations to derive the fluxes of the lobes. Secondly, we re-analyze Chandra observations of the M87 jet with a total exposure time of kiloseconds to explore the X-ray emission characteristics along the jet.
The variabilities of the nucleus and HST-1, as well as the photon spectra for all knots, are investigated. Fitting the radio to X- ray SEDs assuming a synchrotron origin, we show that a broken power-law electron spectrum allows a satisfactory description of the SEDs for most knots except for B, C and D, for which an additional component is needed.
We discuss the implications and suggest that a stratified jet model may account for the differences. Finally, we derive the energy distribution of the ultrarelativistic electron in G1. The electron acceleration is found to be an order of magnitude slower than the maximum rate pro- vided by the shock acceleration in the nominal Bohm diffusion regime.
