Models of jet production in black hole systems suggest that the properties of the accretion disk-such as its mass accretion rate, inner radius, and emergent magnetic field-should drive and modulate the production of relativistic jets. Contemporaneous radio monitoring was done using the Arcminute MicroKelvin Array radio telescope. Two important and simple results are obtained: (1) the jet (as traced by radio flux) does not appear to be modulated by changes in the inner radius of the accretion disk and (2) the jet is sensitive to disk properties, including its flux, temperature, and ionization. Some more complex results may reveal aspects of a coupled disk-corona-jet system. The overall picture that emerges from this study is broadly consistent with some jet-focused models for black hole special energy distributions in which a relativistic plasma is accelerated at z = 10-100 GM/c super(2). We discuss these results in the context of disk-jet connections across the black hole mass scale.
