X-RAY STATES & RADIO JETS (BLACK HOLES)Phenomenology – well understood.

LUMINOSITY CORRELATIONS (BLACK HOLES)No dependence on X-ray binary orbital parameters, nor

outburst properties. Very weak dependence on jet axis.Statistically significant evidence for 2 separate clusters in the

radio/X-ray domain. Universal correlation..no longer such.

BLACK HOLES VS NEUTRON STARSNSs factor ~30 fainter in radioHowever: the most relativistic jet source in the Galaxy is aneutron star

BLACK HOLE SPIN & JET POWERNo apparent relation: IF the measurements are robust (..)=> Jets are not powered by BH rotational energy
