Dust in the wind II: Polarization imaging from disk-born outflows
  In this second research note of a series of two, we aim to map the polarized
flux emerging from a disk-born, dusty outflow as it was prescribed by Elvis
(2000). His structure for quasars was achieved to unify the emission and
absorption features observed in active galactic nuclei (AGN) and can be used as
an alternative scenario to the typical dusty torus that is extensively used to
account for AGN circumnuclear obscuration. Using Monte Carlo radiative transfer
simulations, we model an obscuring outflow arising from an emitting accretion
disk and examine the resulting polarization degree, polarization angle and
polarized flux. Polarization cartography reveals that a disk-born outflow has a
similar torus morphology in polar viewing angles, with bright polarized fluxes
reprocessed onto the wind funnel. At intermediate and edge-on inclinations, the
model is rather close to a double-conical wind, with higher fluxes in the cone
bases. It indicates that the optically thick outflow is not efficient enough to
avoid radiation escaping from the central region, particularly due to the
geometrically thin divergence angle of the outflow. As parametrized in this
research note, a dusty outflow does not seem to be able to correctly reproduce
the polarimetric behavior of an usual dusty torus. Further refinement of the
model is necessary.
