Beaming in Radio-Quiet AGN
(Astronomical Society of the Pacific, 1997)
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 ...
Identification of the exciting source of Herbig-Haro objects 135 and 136
(1997)
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 ...
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 ...
Simultaneous UBVRIJK photometric and polarimetric observations of PQ Gem
(1997)
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 ...
