YITP lunch meeting, Kyoto, 12/12/2007 – slide 2

Long-standing key questions on astrophysical accretion processes

• Growth of supermassive black holes in the early Universe• Intermediate mass black holes in ULXs• Observational evidence for super-Eddington accretion?

Diagnostic power ofthe iron lines on theaccretion process?

• Central mass• Accretion rate• Orientation of

the disk relativeto the observer
