We present UV and optical spectropolarimetry of two highly polarized IRAS-selected quasi-stellar objects (QSOs), IRAS 13349+2438 and the broad absorption line QSO (BALQSO) IRAS 14026+4341. ... We construct full radiative transfer models of these systems consisting of a dusty sphere of modest optical depth illuminated axisymmetrically from within by a power-law QSO spectrum. We show that this simple model successfully reproduces the qualitative polarization properties of the objects. ...

This is a cosmic microwave background (CMB) telelescope with a difference, in that it is designed to survey the sky looking for galaxy clusters by means of the ?shadows? they cast against the CMB. This shadowing, the so-called SZ effect, is a remarkable phenomenon because it is independent of redshift, allowing AMI to find clusters which are so far away that their own emission would be too faint to detect ? ...
