Models of Dusty Discs in Active Galactic Nuclei
(Astronomical Society of the Pacific, 1994)
One of the challenges faced by unified theories for Active Galactic Nuclei (AGN) is to match the observed infrared emission to that predicted for the optically and geometrically thick dusty discs believed to obscure the ...
Discovery of another Am-Herculis Variable in the Period Gap
(1993)
Recently, Buckley et al. drew attention to a new AM Her variable, RE1938 - , discovered by the ROSAT survey with a period of 2.33 h which places it in the middle of the usual 2-3 h period gap for cataclysmic variables. ...
Spectropolarimetry of the ultraluminous infrared galaxy IRAS 110548-1131
(1993)
From spectropolarimetric observations of the galaxy IRAS 110548-1131 we report very strong, broad H-alpha emission (FWHM 7600 km/s) in the polarized flux spectrum. This suggests that IRAS 110548-1131 has an obscured ...
Evidence for an Obscured Broadline Region in the Early Type Radio Galaxy IC5063
(1993)
We report the detection of strong, broad Hα emission seen in polarized flux from the early-type radio galaxy IC 5063. This suggests that the galaxy has a broad-line region which is obscured from our direct view, with the ...
Polarimetry of ST LMi - Discovery of a second accreting pole
(1992)
We have obtained simultaneous multiband photometric and polarimetric light curves for ST LMi (CW1103 + 254) in the visible range and the near-infrared on three occasions. These clearly show the presence of previously ...
Detection of photospheric Zeeman features and cyclotron emission lines in V834 CEN in a low state
(1992)
Simultaneous spectroscopic and polarimetric observations of the AM Herculis system V834 Cen during a low state of accretion are reported. The polarization data show a reversal in the sign of the circular polarization when ...
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) ...
Near-infrared imaging polarimetry of bipolar nebulae. 4: GL-490, GL-2789, GL-2136
(1991)
High spatial resolution near-IR polarization and surface brightness images of the ouflow sources GL 490, GL 2789 and GL 2136 are presented. Polarization vector-maps at J, H and K show centro-symmetric patterns around GL ...
Near-infrared imaging polarimetry of bipolar nebulae 1:the BN-KL region of OMC-1
(1991)
New high-spatial-resolution polarization images of the BN-KL region of OMC-1 from 1.25-3.6 microns are presented. At the longer wavelengths these show a centro-symmetric polarization vector pattern, centered mainly on IRc2, ...
