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 ...
Infrared spectropolarimetry of the galactic-center-magnetic alignment in the discrete sources
(1986)
The results of 8-13 micron spectropolarimetric observations of Galactic Center sources are presented. All the sources show interstellar polarization due to absorption by aligned silicate grains, and these grains appear to ...
