| Description: | Relativistic feedback from compact objects appears to play a major role in the evolution of galaxies, but understanding the accretion conditions that launch jets still remains poorly understood. Nearby compact sources can provide a test bed for studying how accretion disks can launch jets at very different fractions of the Eddington rate. I will present results from X-ray binaries (XRBs), Ultra-luminous sources (ULXs) and the Galactic Centre (Sgr A*), that shows jet production varying over a time scale of a minutes to months; this work provides insight to underlying mass accretion rates and can be used to estimate radiative efficiency of the bolometric luminosity from black hole candidates. Ultimately, with a good calibration of the disk-jet relationship, ALMA and SKA will eventually be able to trace the black hole mass-function in the local universe. |
