[17.34] Exploring the Role of Jets in X-ray Binaries

S. Markoff, M. Nowak (MIT, Center for Space Research), T. Maccarone (SISSA, Trieste)

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 spectrum of X-ray binaries (XRBs) is not yet constrained. Synchrotron 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. In this poster we present some further results, including a possible interpretation for why the optically thick-to-thin turnover in the hard state seems to occur in the same frequency band for many, if not all, sources. We also discuss the trends in our model parameters from fitting various sources, some of which are dominated in the hard X-rays by inverse Compton, and what we can learn about the relationship of the jet to the corona.
