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 ...
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 ...
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. ...
Coordinated multisite observations of the variability of BL Lac
(1985)
The authors present the results of multisite observations of the optical polarization of BL Lac, together with some flux measurements, at a time when BL Lac was relatively faint. The level of polarization varies in a manner ...
