| Abstract: |
X-ray iron line profiles represent an important probe of the geometry and dynamics of the central accretion engine in AGN. Although a flat disk illuminated from above seems to work reasonably well in some cases, the noise in the current data and plausible disk physics invites some consideration of line profiles from non-flat disks for future comparison. Here I discuss some line profiles from concave discs, warped discs, clumpy thick discs, and disks with spiral structure, emphasizing their distinguishing and common features. |
