Searching for the hidden broad-line region in Centaurus A

Alexander, D.M.; Hough, J.; Young, S.; Bailey, J.; Heisler, C.A.; Lumsden, S.; Robinson, A. (1999)

We present the first near-infrared (K-band) spectropolarimetric observations of the nuclear region of Centaurus A. Although the data are of high signal-to-noise ratio, polarized broad Brγ is not detected and we place a 3σ ...

A time-variable scattered component to broad Hα in the Seyfert 1 galaxy Mrk 509

Young, S.; Corbett, S.A.; Giannuzzo, M.E.; Hough, J.; Robinson, A.; Bailey, J.; Axon, D.J. (1999)

We present optical spectropolarimetry data for the Seyfert 1 galaxy Mrk 509 for three epochs: 1996 August and 1997 May and August. We confirm previous findings that broad Hα has a significantly greater width in the polarized ...

Circular Polarization in Star- Formation Regions : Implications for Biomolecular Homochirality

Bailey, J.; Chrysostomou, A.; Hough, J.; Gledhill, T.; McCall, A.; Clark, S.; Menard, F.; Tamura, M. (1998)

Strong infrared circular polarization resulting from dust scattering in reflection nebulae in the Orion OMC-1 star-formation region has been observed. Circular polarization at shorter wavelengths might have been important ...

Near-infrared imaging polarimetry of NGC 1068

Packham, C.; Young, S.; Hough, J.; Axon, D.J.; Bailey, J. (1997)

We present near-infrared polarization images of the nuclear region of NGC 1068. For the first time, extended reflection nebulosity from the south-western cone, which is obscured at optical wavelengths, is detected. Polarized ...

Simultaneous UBVRIJK photometric and polarimetric observations of PQ Gem

Potter, S.B.; Cropper, M.; Mason, K.O.; Hough, J.; Bailey, J. (1997)

We present simultaneous UBVRIJK observations of the intermediate polar PQ Gem (RE J0751+14) obtained on 1993 February 18 and 19 using the Hatfield Polarimeter on UKIRT. The light curves show double- peaked modulation on ...

Identification of the exciting source of Herbig-Haro objects 135 and 136

Tamura, M.; Hough, J.; Chrysostomou, A.; Itoh, Y.; Murakawa, K.; Bailey, J. (1997)

We have identified the exciting source of the Herbig-Haro objects HH135 and 136 by near-infrared polarimetric imaging of the associated extensive reflection nebula. The source is situated at the middle of the two Herbig-Haro ...

Beaming in Radio-Quiet AGN

Young, S.; Hough, J.; Axon, D.J.; Bailey, J. (Astronomical Society of the Pacific, 1997)

We have obtained new optical spectropolarimetric data for the radio-quiet Seyfert NGC 1068, taken through apertures on the nucleus and at two positions within the ionization/scattering cone. The equivalent width of scattered ...

Optical and near-infrared spectropolarimetry of the infrared-luminous galaxy IRAS 23060+0505

Young, S.; Hough, J.; Axon, D.J.; Ward, M.J.; Bailey, J. (1996)

We present optical and near-IR spectropolarimetry of the type 2 infrared-luminous galaxy IRAS 23060+0505, which clearly shows both broad Hα and Paalpha in polarized flux. The full widths at half maximum (FWHM) of these ...

Near-infrared and millimetre polarimetry of CEN A

Packham, C.; Hough, J.; Young, S.; Chrysostomou, A.; Bailey, J.; Axon, D.J.; Ward, M.J. (1996)

We present near-infrared polarization images of the nuclear region of CenA, and millimetre polarimetry of the nucleus. In the near-infrared the polarization vectors mainly lie along the dust lane, with the polarization ...

Dust in a Hostile Environment: Interstellar Dust in the Line of Sight to HD62542

Magalhaes, A.M.; Rodrigues, C.V.; Meade, M.; Code, A.D.; Nordsieck, K.H.; Anderson, C.M.; Bailey, J.; Hough, J.; Wheatley, P.J. (Astronomical Society of the Pacific, 1996)

HD 62542 is situated in a line of sight toward a ridge of dark matter in the Gum Nebula. That region is under the influence of UV radiation and stellar winds from hot stars. We use for the first time interstellar polarization ...
