Iron Line Profiles from Relativistic Thick Accretion Disk

We present a new code for calculating the Fe Kalpha line profiles from relativistic accretion disks with finite thicknessaround a rotating black hole. The thin Keplerian accretion disk must become thicker and sub-Keplerian with increasing accretion rates. We here embark on, for the first time, a fully relativistic computation which is aimed at gaining an insight into the effects of geometrical thickness and the sub-Keplerian orbital velocity on the line profiles. This code is also well-suited to produce accretion disk images.
