Exploring the Jet/Accretion Flow Relationship in Low Disk Luminosity Sources

AbstractAstrophysical jets seem to gain strength disproportionate to the power of their associated accretion flow, making low-luminosity sources ideal targets for studies of the role of outflows. Radio/X-ray correlations have supported the case for a strong relationship between the jets and the hard X-ray emitting regions, and here we explore the strongest scenario where the base of the jets subsumes the role of the corona. The properties of coronae, as inferred from spectral models, are very similar to what is empirically required at jet bases assuming conservation laws hold. We present a few preliminary fits to simultaneous radio and X-ray data sets from our GX 339-4 and Cyg X-1 campaigns. The fits are performed in detector space, and include a jet plus thermal disk continuum model, with added Gaussian line and non-relativistic reflection features similar to the approach of other X-ray models. We find that we can fit the entire radio through X-ray spectrum quite well, with any deviation occurring in the line/reflection region. The results suggest that a jet/corona unification can provide a reasonable description of the data. Future work will benefit from a more complex approach to the disk feedback features.
