The Iron Line Profile from Warped Black Hole Accretion Disks

The profile of the fluorescent iron line from black hole accretion disks is a powerful diagnostic properties, such as spin and inclination. state-of-the-art, however, considers an disk whose angular momentum aligned with that hole; this very constraining assumption which unlikely to apply many or even most astrophysical systems. Here, we present first simulation reflection spectrum warped using realistic model reflected emission based on xillver code. We effects radial location warp tilt angle have profile, highlight results are highly dependent azimuth position observer relative angle. fit these profiles in XSpec standard relxill lamppost quantify effect neglecting warps has inferred spins inclinations. show fits two-component can be used derive more accurate inclination estimates.
