An optical and near-infrared polarization survey of Seyfert and broad-line radio galaxies. 2 : the wavelength dependence of polarization
(1990)
We discuss the wavelength dependence (0.44-2.2 micron) of polarization of the sample of 71 Seyfert and three broad-line radio galaxies presented in Paper I. For four galaxies, 3A 0557-353, Fairall 51, IC 4329A and NGC 3753, ...
Spectropolarimetry of the molecular-hydrogen line emission from OMC-1
(1988)
Observations of the H2 v = 1-0 S(1) line at 35 km/s velocity resolution were obtained at several locations within OMC-1, including the molecular hydrogen reflection nebula. All line profiles are smooth and show no evidence ...
The polarization of NGC 1068
(1988)
Broad-band polarimetry of NGC 1068 over the wavelength range 0.36 - 4.8 μm is presented, together with high-resolution spectropolarimetry of the Hβ, [O III] and Hα, [N II] regions of the spectrum. The authors recognize ...
Infrared polarization in OMC-1 - Discovery of a molecular hydrogen reflection nebula
(1986)
The polarization of the broadband continuum at K has been mapped in the core of the OMC-1 with high spatial resolution, and with lower resolution in a more extensive surrounding area. In addition, the first detailed ...
Simultaneous optical and infrared polarization measurements of blazars
(1986)
The authors present measurements of the polarization and flux of a sample of 28 blazars (21 BL Lacs and 7 OVV quasars) at optical and near-infrared wavelengths, with repeated observations for some objects. As in earlier ...
Infrared polarimetry of the nucleus of Centaurus A - The nearest blazar?
(1986)
As one of the nearest examples of an active galaxy, NGC5128 (Centaurus A) has been studied in detail over a wide range of wavelengths. The nucleus of the galaxy is seen clearly in the X-ray, radio and infrared, but is ...
The origin of the visual and infrared pulsations in the intermediate polar FO AQR (H2215-086)
(1986)
Simultaneous visual and infrared polarimetry of the intermediate polar FO Aqr (H2215-086) shows that its visual and infrared pulsations, seen at the rotation period of the white dwarf, are not circularly polarized. This ...
Infrared photometry of the nuclei of early-type radio galaxies
(1986)
The authors have obtained near- and mid-infrared photometry of the nuclei of both strong and weak radio galaxies. The implication of these data are that a relatively small percentage, ≅15 per cent, of radio ellipticals ...
An optical and near-infrared study of the AM Herculis-type binary CW 1103+254
(1985)
All main components of the AM Herculis-type binary CW 1103 + 254 can be distinguished by means of observations encompassing optical and near-IR photometry and polarimetry, together with optical spectroscopy and spectropolarimetry. ...
