✦ Synopsis

While we know jets play an active role in both the emission and dynamics of active galactic nuclei, the extent of their contribution to the high-energy spectra of X-ray binaries (XRBs) and low-luminosity AGN (LLAGN)

is not yet constrained. Synchrotron radiation from a jet has been shown capable of explaining the broadband hard state emission of XRBs, as well as the radio/X-ray correlations seen now in several sources. We discuss the trends in our model parameters from fitting a number of stellar and galactic sources, some of which we find to be dominated in the hard X-rays by inverse Compton, and what we can infer about the relationship of the jet to the corona/disk. For XRBs, we present some ideas about why the optically thick-to-thin turnover in the hard state seems to always occur in the same frequency range. Finally, we discuss the effect of the jet being misaligned from the outer disk.
