Polarimetric mapping of a new infrared reflection nebula GGD 27 IRS
(1987)
We report the discovery of an infrared reflection nebula GGD27 IRS, near the optical nebulosity GGD27. It shows a dumbbell-shaped structure with large degrees of polarization, up to 64%, in the K band. From the centrosymmetric ...
Magnetic field structure in dark clouds
(Reidel Publishing Company (Kluwer Imprint), 1987)
Interstellar polarization in the dust lane of Centaurus A (NGC 5128)
(1987)
Optical and infrared linear polarization measurements of the Type 1 supernova 1986G in Centaurus A are used to determine the wavelength dependence of polarization produced by transmission of radiation through the dust lane ...
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 ...
Infrared polarimetry of the reflection nebula near L 1551 IRS 5
(1986)
The K-band polarization has been measured in the region extending 30 arcsec to the SW of L 1551 IRS 5. The degree of polarization is exceptionally high, reaching ≡67 per cent. The large polarizations and the azimuthal ...
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 ...
