Abstract: |
We study AGN emission line profiles combining an improved version of
the accretion disk wind model of Murray & Chiang (1997) with the
magnetohydrodynamic (MHD) model of Emmering et al. (1992). We find
that the shape, broadening and shift of the C IV line depend
not only on the viewing angle to the object, but also on the wind
launch angle.
We have compared the dispersions in our model C IV linewidth
distributions to the
observed upper limit on that dispersion found by
Fine et al. (2008, 2010).
We have considered both an opaque torus of fixed half-opening angle
and the physically
motivated obscuration model of Mor et al. (2009).
As the torus half-opening angle
increases above about 18°, increasingly larger wind launch
angles are
required to match the Fine et al. constraints. Above a half-opening
angle of about 47°, no wind launch angle can match the
observations. |
