CONCLUSION Microquasars have provided insight into: :  CONCLUSION Microquasars have provided insight into: THE PHYSICS OF RELATIVISTIC JETS FROM BH’s THE CONNECTION BETWEEN ACCRETION & EJECTION THE FORMATION OF STELLAR-MASS BLACK HOLES Microquasars could provide insight into: A LARGE FRACTION OF ULXs IN NEARBY GALAXIES GRBs OF LONG DURATION IN DISTANT GALAXIES X-RAY - RADIO CORRELATIONS IN LOW-POWER BHs OF ALL MASSES:  X-RAY - RADIO CORRELATIONS IN LOW-POWER BHs OF ALL MASSES Radio-X-ray correlation in low-hard state mQSOs (Corbel et al. 02; Gallo, Fender & Pooley, 03; Maccarone et al.03) The power output of quiescent BHs is jet-dominated In high-soft X-ray state the radio jets are quenched. Also in AGN. Sgr A*, LINERs, FR I & BL Lac are analogous to mQSOs in the low-hard state (Falcke,et al. 04) Relation between X-ray, radio & mass of BHs 5 GHz & 2-10 keV core emission (Merloni, Heinz & Di Matteo 03) From radiativelly inefficient accretion rather than thin synchrotron Radio/bolometric luminosity larger in AGN (Heinz & Sunyaev 2003) If more robust, independently of the model THE MASS OF BLACK HOLES COULD BE INFERRED TIME VARIATIONS SEEM TO SCALE WITH BLACK HOLE MASS:  TIME VARIATIONS SEEM TO SCALE WITH BLACK HOLE MASS 1) Duration of X-ray flares in Cyg X-1 and Sgr A* In Cyg X-1 and other BHXRBs: 1-10 ms (Gierlinski & Zdziarski, 03) In Sgr A* 400-10,000 s (Baganoff et al. 01; Goldwurm et al. 03) 2) 3:2 twin peak kHz QPO in mQSOs and the spin of BHs In 3 mQSOs a = J/(GM/c2) = 0.6-0.9 (Remillard 2004) Due to gravitational cyclic modes (Abramowicz et al. 2004) Observations in Sgr A* : IR QPOs of ~17 min  a = 0.52 (Genzel et al. Nature. 04) X-ray QPOs that include twins of 12 & 19 min (Aschenbach et al. 04). DT ratio ~ MSgrA BH / Mstellar BH = 105-6 Independently of the model The BH mass in ULXs may be derived Strohmayer GRS 1915+105 APERIODIC VARIABILITY IN AGN & mQSOs :  APERIODIC VARIABILITY IN AGN & mQSOs The break time scale in the power spectral density of black holes seems to scale linearly with the mass of the BH (Uttley & McHardy, 2001) The NLS1 NGC 4051 scales better with Cyg X-1 in the soft-high state (Lbol ~ 0.3 Ledd) The broad band Sey 1 NGC 3516 scales linearly with Cyg X-1 in the low-hard state (McHardy, 04) Most of the aperiodic variation in Cyg X-1 is due to the harder component (Churazov, Gilfanov, Revnivtsev, 2001) Propagating perturbations in the accreting flow (Uttley, 2004) THE MASS OF BLACK HOLES IN ULXs COULD BE DETERMINED QPOs AND GENERAL RELATIVITY:  QPOs AND GENERAL RELATIVITY GRS 1915+105 (Strohmayer) nmax = f(MBH, Spin)  DETERMINE THE SPIN OF BLACK HOLES THE BH SPIN & DISK TEMPERATURE SUGGEST THAT JETS MAY BE POWERED BY THE BH SPIN (Zhang et al.; Wang) High frequency QPOs (e.g. 40 & 67 Hz repeat in GRS) This 3:2 ratio now found in 4 BHXBs (Remillard et al.)  must depend on fundamental properties of black hole Tagger; Chakrabarti, Zhang
