Reprocessed emission from warped accretion disks
We present the profiles of reprocessing emission lines originating in a relativistic, warped accretion disk around a non-rotating black hole. Our calculations are aimed at providing a possibility that the variability of double-peaked emission line which can not be explained by a circular Keplerian disk may be induced by disk warping. The warped disk can also provide a solutoin for the energy budget problem due to the disk warping can enhance the solid angle of the outer disk portion subtended to the inner part of the disk. In the calculation a parameterize disk geometry and a central point-like source of ionizing radiation are adopted. We find that the ratio between the red and blue peaks of the line profiles cross unity can be naturally predicted by a twisted warp disk, and a third peak can be produced in some cases.
