  31. SUMMARY 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 STARS NSs factor ~30 fainter in radio However: the most relativistic jet source in the Galaxy is a neutron star BLACK HOLE SPIN & JET POWER No apparent relation: IF the measurements are robust (..) => Jets are not powered by BH rotational energy
