Accretion rate increases with z for all mass
BHs See also very interesting result by Y.M. Chen
et al about duty cycle

The Fundamental Plane Relationship of
Astrophysical Black Holes
  • Ran Wang
  • Alessandro Marconi

Can this be generalized to AGN?

Accretion disk stamp
Omer Blaes
It is all magnetically driven
Please Omer Will you give us back our corona? The
X-ray astronomers
12
Undressing AGNs
Why is this different from Seyfert 1s (Paulina
Lira)? Can the BLR provide the mysterious screen?

Relativistic disk lines
Tahir Yaqoob 1. 25-50 of all AGNs show
relativistic disk lines - ??? 2. We are trying
hard but so far have not succeeded in measuring
black hole spin

Jane Turner Relativistic narrow lines are common
and VERY strong !

Major questions
Jian-Min Wang
  • jet formation/ejection from disk
  • are they really connected?
  • how to form and quench?
  • how to accelerate jets?
  • jet fraction of the energy
  • output from BH accretion?
  • jet formation is BH mass-scale free?
  • jet component?
  • jet interaction with surrounding photons from
    disk, BLR?

Emission-Line Profiles at Low Flux Levels
Mike Crenshaw
24
Simple Geometric Model
  • r 0.1 pc, ? 45?, vr vlos - 490 km s-1
  • Assume v? 0, then v? vT 2100 km s-1 (vT
    10,000 km s-1 also shown)

25
Do we really need that level of
sophistication? (the case of stellar winds)
  • Asymmetric UV emission lines
  • Symmetric X-ray lines

Owocki et al.
26
More winds
  • M. Guainazzi WA is also warm reflector (but 200
    pc large)
  • F. Nicastro WA is lt0.1 pc in size
  • Goncalves He-like X-ray lines are good wind
    diagnostics

27
Broad Line Region stamp
  • Joe Shields
  • What is the physical origin of the Baldwin effect
    (29 years is not enough..)
  • M. Joly
  • What is the origin of the extremely strong FeII
    lines (26 years is not enough ..)

More BLR goodies
  • B. Welsh BLR gas is falling in (??)
  • I. Strateva double-peaked line profiles
  • F. Hamann BLR metallicity goes with BH mass (but
    L/L(Edd) and time dependence)
  • The SDSS industry (or what can we learn by
    studying large samples?) - Nagao
