| Abstract: |
The blue-shifted broad emission lines and/or broad absorption lines
seen in many luminous quasars are striking evidence for a broad line
region in which radiation driving plays an important role. We
consider the case for a similar role for radiation driving beyond the
dust sublimation radius by focussing on the infrared regime where the
relationship between luminosity and the prominence of the 3–5μm
bump may be key. To investigate this further, we apply the 3D
hydrodynamic wind model of Everett (2005) to predict the infrared
spectral energy distributions of quasars. The presence of the
3–5μm bump and strong, broad silicate features can be
reproduced with this dynamical wind model when radiation driving on dust is
taken into account. |
