A long standing interest has been the question of what AGN disks should look like. I have concentrated on the thermal emission from accretion disks, including the energy distribution and polarization. Recently I have been particularly interested in the strong polarization observed by HST in the Lyman continuum of some QSOs.
The paper "Powerful Flares from Recoiling Black Holes in Quasars" (G. A. Shields and E. W. Bonning 2008, ApJ 682:758) discusses a numerical simulation of an accretion disk disrupted by a recoiling black hole. An animation of the numerical simulation is here.
