Empirical Links between XRB and AGN Accretion Processes
• all spectral types show negative correlation--even the LINERs and HIIsADAF could be the dominant accretion process in the low L/Ledd
All spectral classes of NELGs show negative G− L/Ledd correlation
Location of inflection point is independent of:
- range of Mbh
- optical spectral class
-X-ray activity-morphology-…
• − L/Ledd is non-monotonic: changes sign at log Lx/Ledd ~ -3.5• strong connection in the accretion physics of AGN and XRBs!
COMING SOON: • Simultaneous constraints on continuum and absorption in X-ray data.• Include radio data; investigate relationship of jet activity to accretion• check − L/Ledd relationship as a function of environment.
SUMMARY (i.e., homework for theoretical modeling of AGN accretion)
