We present a method for calculating the infrared polarization due to absorption and emission by aligned grains distributed in a disc or a torus. The temperature distribution in the torus is calculated with the axially ...

We present near-infrared polarization images of the nuclear region of NGC 1068. For the first time, extended reflection nebulosity from the south-western cone, which is obscured at optical wavelengths, is detected. Polarized ...

We present simultaneous UBVRIJK observations of the intermediate polar PQ Gem (RE J0751+14) obtained on 1993 February 18 and 19 using the Hatfield Polarimeter on UKIRT. The light curves show double- peaked modulation on ...

We have identified the exciting source of the Herbig-Haro objects HH135 and 136 by near-infrared polarimetric imaging of the associated extensive reflection nebula. The source is situated at the middle of the two Herbig-Haro ...

Polarimetry at near-infrared wavelengths is shown to be an important tool in understanding the properties of the obscuring torus in NGC1068. We present evidence for the existence of aligned grains in the torus, which produce ...

We have obtained new optical spectropolarimetric data for the radio-quiet Seyfert NGC 1068, taken through apertures on the nucleus and at two positions within the ionization/scattering cone. The equivalent width of scattered ...

One of the main uses of polarimetry over the last decade has been to identify the nature of AGN that are normally hidden from direct view by an optically and geometrically thick torus, and thereby to unify different classes ...
