  • Bailey, J.; Cunningham, C.; Hough, J.; Axon, D.J. (1981)
    Observations of the polarization of Mrk 421 in the V, J, and K bands are presented. The infrared radiation shows variable polarization with a range of at least 2-4%. The spectrum of the nonthermal source in the VJK regions ...
  • Parsons, H.; Thompson, M.A.; Chrysostomou, A. (2009)
    We present an investigation of candidate infrared dark cloud (IRDC) cores as identified by Simon et al. located within the Submillimetre Common User Bolometer Array (SCUBA) Legacy Catalogue. After applying a uniform noise ...
  • Good, Elizabeth; Kong, Xin; Embury, Owen; Merchant, Chris; Remedio, John (2012)
    A new aerosol index for the Along-Track Scanning Radiometers (ATSRs) is presented that provides a means to detect desert dust contamination in infrared SST retrievals. The ATSR Saharan dust index (ASDI) utilises only the ...
  • Tansley, D.; Birkinshaw, M.; Hardcastle, M.J.; Worrall, D.M. (2000)
  • Murdoch, K.A.; Drew, J.E.; Anderson, L.S. (1994)
  • Blackwell-Whitehead, R.; Pavlenko, Y. V.; Nave, G.; Pickering, J.C.; Jones, H.R.A.; Lyubchik, Y.; Nilsson, H. (2011)
    Aims: The aim of our new laboratory measurements is to measure accurate absolute oscillator strengths for neutral manganese transitions in the infrared needed for the study of late-type stars and ultracool dwarfs. Methods: ...
  • Riaz, Basmah; Gizis, John E. (2007-04-10)
    We present Spitzer/IRAC observations of the L5 dwarf, 2MASSI J1315309-264951 (2M 1315). This ultracool dwarf is known to display strong emission in the H alpha line. The spectral energy distribution (SED) for this object ...
  • Litchfield, S.~J.; Robson, E.~I.; Stevens, Jason (1994-09-01)
    We present photometric observations of 16 blazar sources at mid- to near- infrared wavelengths, covering the period 1986 January to 1993 December. We present the data in tabular form and, for selected well-sampled sources, ...
  • Sparks, W.; Hough, J.; Axon, D.J.; Bailey, J. (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 ...
  • Lowe, K. (2008-10-20)
    In this thesis, I present the properties of IRAS 19306+1407 central source and its sur- rounding circumstellar envelope (CSE), from the analysis of near-infrared (near-IR) polarimetry and integral field spectroscopy ...
  • Hough, J. (1997)
    Polarimetry at near-infrared wavelengths is shown to be an important tool in understanding the properties of the obscuring torus in NGC1068. We present evidence for the existence of aligned grains in the torus, which produce ...
  • 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, ...
  • Hough, J.; Aitken, D. (2005)
    Grains in the diffuse interstellar medium, and in at least some parts of dense molecular clouds, are aligned with their short axis preferentially along the direction of the local magnetic field. At longer infrared wavelengths ...
  • Bailey, J.; Sparks, W.; Hough, J.; Axon, D.J. (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 ...
  • Nagata, T.; Yamashita, T.; Sato, S.; Suzuki, H.; Hough, J.; Garden, R.; Gatley, I. (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 ...
  • Fujiyoshi, T.; Smith, C.H.; Wright, C.M.; Moore, T.J.T.; Aitken, D.; Roche, P.F. (2001)
    We present 8-13μm spectropolarimetry, and 12- and 2-μm imaging polarimetry of the southern massive star-forming region G333.6−0.2. Spectro-polarimetry measurements show that the polarization observed towards the 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 ...
  • Bond, Nicholas A.; Benford, Dominic J.; Gardner, Jonathan P.; Amblard, Alexandre; Fleuren, Simone; Blain, Andrew W.; Dunne, Loretta; Smith, Daniel; Maddox, Steve J.; Hoyos, Carlos; Baes, Maarten; Bonfield, David; Bourne, Nathan; Bridge, Carrie; Buttiglione, Sara; Cava, Antonio; Clements, David; Cooray, Asantha; Dariush, Ali; de Zotti, Gianfranco; Driver, Simon; Dye, Simon; Eales, Steve; Eisenhardt, Peter; Hopwood, Rosalind; Ibar, Edo; Ivison, Rob J.; Jarvis, M.J.; Kelvin, Lee; Robotham, Aaron S. G.; Temi, Pasquale; Thompson, Mark; Tsai, Chao-Wei; van der Werf, Paul; Wright, Edward L.; Wu, Jingwen; Yan, Lin (2012-05-01)
    We describe the infrared properties of sources detected over similar to 36 deg(2) of sky in the GAMA 15 hr equatorial field, using data from both the Herschel Astrophysical Terahertz Large-Area Survey (H-ATLAS) and Wide-field ...
  • Wilman, R. J.; Jarvis, M.J.; Mauch, T.; Rawlings, S.; Hickey, Samantha (2010-06-11)
    To exploit synergies between the Herschel Space Observatory and next generation radio facilities, we have extended the semi-empirical extragalactic radio continuum simulation of Wilman et al. to the mid- and far-infrared. ...
