Across thirteen black hole X-ray binaries, type-A QPOs show negative lags and often precede radio flares, type-B QPOs accompany the flares, and inferred soft-intermediate-state jet velocities are moderately relativistic.

abstract
I discuss the energetics of synchrotron-emitting outflows, increasingly found to be present in many different classes of X-ray binary systems. It is shown that the outflow is likely to be comparable in power to the integrated X-ray luminosity, traditionally taken to be an indicator of the global mass-transfer rate. This is especially found to be the case in the (low/)hard states of black hole candidate systems. I conclude that jets are extremely important, energetically and dynamically, for the accretion process in the majority of known X-ray binary systems.

Revisiting Disc-Jet Coupling in Black Hole X-ray Binaries: On the Nature of Disc Dynamics and Jet Velocity
Across thirteen black hole X-ray binaries, type-A QPOs show negative lags and often precede radio flares, type-B QPOs accompany the flares, and inferred soft-intermediate-state jet velocities are moderately relativistic.
