abstract:

    line_1:        Our ground-based spectrophotopolarimetry shows that nearly half of a small
    line_2:        sample of the most luminous IRAS AGN (L > 10^11 L(suns)) are highly polarized
    line_3:        (up to p% = 25%) and the polarization is strongly wavelength dependent. For
    line_4:        several we observe a typical QSO spectrum in polarized light suggesting the
    line_5:        axisymmetric geometry proposed for lower luminosity AGN like NGC 1068. We
    line_6:        propose to use spectropolarimetry with the FOS
    line_7:        to investigate the nature of the polarization in this UNIQUE sample of highly
    line_8:        polarized IRAS-selected IR-ultraluminous AGN, and thereby constrain the nuclear
    line_9:        geometry and investigate the `hidden QSO' hypothesis. HST will provide the wide
    line_10:       wavelength coverage needed to discriminate among different polarization
    line_11:       mechanisms, and extend our ground-based spectropolarimetry to ~1650 A. Imaging
    line_12:       will help constrain the geometry of the scatterers, which is important for
    line_13:       detailed investigation of their properties. Better understanding of selection
    line_14:       biases caused by dust will be important in understanding the space density and
    line_15:       evolution of AGN.
