The broad iron line, seen in the X-ray spectra of many AGN,
is thought to originate from the inner regions of the black
hole accretion disk. I will summarize recent developments in
using this line to probe the accretion disk structure, as
well as the mass and spin of black holes in Seyfert
galaxies. In particular, I will present observational
evidence suggesting that the inner regions of the accretion
disks in low-luminosity AGN (LLAGN) are distinctly different
from those in higher-luminosity AGN. This tentative result
lends support to models of LLAGN based upon advective
accretion disks.
This work was primarily supported through the Hubble
Fellowship Program.
