Description
It has been found that a complex non-linear correlation exist between the X-ray and radio bands of accreting stellar-mass black holes. As the outflow of relativistic particles is dependent on the inflow of matter, high-resolution (milli-arcsecond) radio imaging has been used to resolve the outflow at different X-ray spectral states. By identifying when a steady compact jet is present, a fundamental relationship between the inflow and outflow has been shown to depend on the overall mass accretion rate around the black hole. Moreover, evidence will be presented that a 'turn-over' in the radiative efficiency of an accretion disk exists, where below a critical accretion rate, the inflow becomes radiatively in-efficient and can be best described via advection dominated models.
