An optical and near-infrared polarization survey of nearby starburst and interacting galaxies
(1991)
Broadband optical and near-infrared polarization and flux density measurements of a sample of 27 starburst and interacting galaxies are presented. The observed polarizations are generally small (P is less than 1 percent) ...
An optical and near-infrared polarization survey of Seyfert and broad-line radio galaxies. 1 : statistical properties
(1990)
The present broad-band and near-IR flux density and polarization measurements of a sample of 71 Seyfert galaxies and three broad-line radio galaxies confirms earlier indications that the polarization of Seyferts is generally ...
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, ...
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 ...
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 ...
