Galactic jet sources and the AGN connection.
FALCKE H. and BIERMANN P.L.
Abstract (from CDS):
In order to further test our hypothesis that jets and disk around compact accreting objects are symbiotic features we investigate the newly discovered superluminal galactic radio jets GRS 1915+105 and GRO J1655-40 and other galactic radio jets like 1E1740-2942, GRS 1758-258 and SS 433 within the framework of our coupled jet/disk model developed initially for active galactic nuclei (AGN) and the galactic center source Sgr A*. By comparing the "disk" and radio core luminosity of those galactic jet sources with our model prediction we can show that they can easily be understood as AGN-like jets where the accretion power onto a central compact object is scaled down by several orders of magnitude. The total power of the jets must be comparable to the disk luminosity - at least for the superluminal sources. To broaden our view we also shortly discuss the situation in other galactic flat spectrum radio sources associated with compact objects - the X-ray binaries Cyg X-1, Cyg X-2, Cyg X-3, Sco X-1, Cir X-1 - where a jet origin has been proposed earlier on theoretical grounds. In a disk/radio luminosity diagram their radio cores also fall within our model prediction for scaled down radio loud and radio weak AGN-jets. Taking all sources together and comparing their L_ disk_/radio ratio we find an indication for a similar radio loud/radio weak dichotomy as found earlier for quasar radio cores, however, a larger number of galactic jet sources is needed to confirm this trend.
