Are jet speeds governed by accretion modes?

Abstract Relativistic jets are observed in both stellar-mass black hole X-ray binaries (BHXRBs) and active galactic nuclei (AGNs), yet their bulk Lorentz factors differ systematically—those in black hole X-ray binaries are typically below ~2, whereas AGN jets can reach ~50. The o...
