(2008)
      The INT/WFC Photometric Hα Survey of the Northern Galactic Plane (IPHAS) is an imaging survey being carried out in Hα, r′ and i′ filters, with the Wide Field Camera (WFC) on the 2.5-m Isaac Newton Telescope (INT) to a depth ...

    • IPHAS A-type stars with mid-infrared excesses in Spitzer surveys 

      Hales, A.; Barlow, M.J.; Drew, J.E.; Unruh, Y.C.; Greimel, R.; Irwin, M.J.; Gonzalez-Solares, E. (2009)

    • Near-infrared imaging polarimetry of dusty young stars 

      Hales, A.; Gledhill, T.; Barlow, M.J.; Lowe, K. (2006)

    • Near-Infrared Imaging Polarimetry of HD142527 

      Canovas, H.; Menard, F.; Hales, A.; Jordan, A.; Schreiber, M. R.; Casassus, S.; Gledhill, T.; Pinte, C. (2013-08)
      HD 142527 is a pre-transition disk with strong evidence for on-going planet formation. Recent observations show a disrupted disk with spiral arms, a dust-depleted inner cavity and the possible presence of gas streams driving ...

    • Near-IR imaging Polarimetry of Dust-debris Disk Candidates 

      Hales, A.; Barlow, M.J.; Gledhill, T. (Astronomical Society of the Pacific, 2005)
      We have carried out JHK polarimetric observations of ten stars around which dust-debris disks may be present, by using the polarimeter module IRPOL2 with the near-IR camera UIST on UKIRT. Our sample targeted systems for ...
