Near-infrared imaging polarimetry of Cygnus A
(1998)
We present a 2.2-μm polarization image of the nuclear regions of Cygnus A. The degree of polarization in the central 1 arcsec is (4.1±0.50) per cent, at a position angle of (23.6±3.6)°, approximately perpendicular to the ...
Near-infrared imaging polarimetry of NGC 1068
(1997)
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 ...
Near-infrared and millimetre polarimetry of CEN A
(1996)
We present near-infrared polarization images of the nuclear region of CenA, and millimetre polarimetry of the nucleus. In the near-infrared the polarization vectors mainly lie along the dust lane, with the polarization ...
