Infrared polarimetry of dark clouds. II : Magnetic field structure in the Rho Ophiuchi dark cloud
Sato, S.; Tamura, M.; Nagata, T.; Kaifu, N.; Hough, J.; McLean, I. (1988)K-band polarimetry of 20 sources embedded within the densest region of the Rho Oph dark cloud has been obtained. The degree of polarization ranges from 1.1 to 7.4 percent, and the position angles have a bimodal distribution, ... -
Infrared polarization in OMC-1 - Discovery of a molecular hydrogen reflection nebula
Hough, J.; Axon, D.J.; Burton, M.; Gatley, I.; Sato, S.; Bailey, J.; McCaughrean, M.J.; McLean, I.; Nagata, T.; Allen, D.; Garden, R.; Hasegawa, T.; Hayashi, M.; Kaifu, N.; Morimoto, M.; Walther, D. (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 ... -
Magnetic field structure in dark clouds
Tamura, M.; Nagata, T.; Sato, S.; Tanaka, M.; Kaifu, N.; Hough, J.; McLean, I.; Gatley, I.; Garden, R.; McCaughrean, M.J. (Reidel Publishing Company (Kluwer Imprint), 1987) -
An optical and near-infrared polarization survey of Seyfert and broad-line radio galaxies. 1 : statistical properties
Brindle, C.; Hough, J.; Bailey, J.; Axon, D.J.; Ward, M.J.; Sparks, W.; McLean, I. (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
Brindle, C.; Hough, J.; Bailey, J.; Axon, D.J.; Ward, M.J.; Sparks, W.; McLean, I. (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, ... -
An optical and near-infrared study of the AM Herculis-type binary CW 1103+254
Bailey, J.; Watts, D.J.; Sherrington, M.R.; Axon, D.J.; Giles, A.B.; Hanes, D.A.; Heathcote, S.R.; Hough, J.; Hughes, S.; Jameson, R.F.; McLean, I. (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. ... -
Polarimetric mapping of a new infrared reflection nebula GGD 27 IRS
Yamashita, T.; Sato, S.; Nagata, T.; Suzuki, H.; Hough, J.; McLean, I.; Garden, R.; Gatley, I. (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 ... -
The polarization of NGC 1068
Bailey, J.; Axon, D.J.; Hough, J.; Ward, M.J.; McLean, I.; Heathcote, S.R. (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 ... -
Spectral analysis of high resolution near-infrared spectra of ultra cool dwarfs
Lyubchik, Y.; Jones, H.R.A.; Pavlenko, Y.; Martin, E.L.; McLean, I.; Prato, L.; Barber, R.J.; Tennyson, J. (2007) -
Spectropolarimetry of the molecular-hydrogen line emission from OMC-1
Burton, M.; Hough, J.; Axon, D.J.; Hasegawa, T.; Tamura, M.; McCaughrean, M.J.; McLean, I. (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 ...
