Polarimetry and modelling of narrow-line active galaxies
(1996)
We present optical spectropolarimetry along with optical and infrared broad-band filter polarimetry of selected warm [f(25 μm)/f(60 μm)>=0.3] IRAS galaxies and other known Seyfert 2 galaxies. Broad lines in polarized flux ...
The appearance of broad H alpha in BL Lacertae
(1996)
We present optical spectropolarimetry confirming Vermeulen et al.'s recent discovery of a broad Hα emission line in BL Lacertae. This feature, which is present at about the same strength in spectra taken two days apart, ...
Powering the Broad H alpha Line in BL Lacertae
(Astronomical Society of the Pacific, 1996)
Optical and near-infrared spectropolarimetry of the infrared-luminous galaxy IRAS 23060+0505
(1996)
We present optical and near-IR spectropolarimetry of the type 2 infrared-luminous galaxy IRAS 23060+0505, which clearly shows both broad Hα and Paalpha in polarized flux. The full widths at half maximum (FWHM) of these ...
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 ...
Near-IR spectropolarimetry and modeling of NGC 1068
(1995)
We present new spectropolarimetric data for NGC 1068, including, for the first time, coverage in the near-IR. Using these, and other previously published data, we develop a scattering model for NGC 1068, using NGC 5548 for ...
High Resolution Studies of Molecular Hydrogen by Means of Near-Infrared Fabry-Perot Imaging
(Astronomical Society of the Pacific, 1995)
We present a study of the velocity profiles of the v=1-0 S(1) transition of molecular hydrogen (H2) towards the star forming region of OMC-1. A three dimensional data cube is presented which displays the spatial distribution ...
Spatially Resolved Spectropolarimetry of NGC 1068
(Astronomical Society of the Pacific, 1994)
A turning point in the study of AGN was the discovery of broad hydrogen lines seen in polarized light in the nucleus of NGC 1068 (Antonucci and Miller 1985). A model was developed whereby the scatterers responsible for ...
Hidden broad-line regions and anisotropy in AGN
(1994)
We discuss the recent advances made in the search for hidden broad line regions in Seyfert and Narrow Line Radio Galaxies (NLRG) using both spectropolarimetry and infrared spectroscopy/spectropolarimetry. Two important ...
Near-IR Spectropolarimetry of NGC 1088
(Astronomical Society of the Pacific, 1994)
The current unified model of Seyfert galaxies, as proposed by Antonucci and Miller (1985), has most, if not all, Seyfert 2 galaxies hosting a Seyfert 1 type nucleus in their cores. The broad lines from the type 1 nucleus ...
