We propose to obtain 5.6-16 mu spectro-photometry with CAM CVF and
photometry with PHOT of a sample of 5 AGN that show broad lines in
polarized flux.
Our main scientific objective is to model the emission from the torus
surrounding the nucleus using the detailed radiative transfer codes
developed by Efstathiou & Rowan-Robinson (1995). Such calculations
have shown that the spectra emitted by the torus are very sensitive to
orientation, and other assumed parameters, in the mid-infrared,
especially around the 10 mu silicate feature.
Modeling of the data will enable us to determine physical parameters
of the torus, including dust composition. IT IS IMPORTANT TO NOTE THAT
OUR OBJECT LIST ONLY INCLUDES SOURCES FOR WHICH WE HAVE OPTICAL
POLARIZATION DATA THAT ALLOW US TO CONSTRAIN THE MODELS: e.g. from the
intrinsic polarisation, as determined from broad band and
spectropolarimetry data, we can determine the orientation of the
torus.
