    • The HO Southern Galactic Plane Survey (HOPS) - I. Techniques and HO maser data 

      Walsh, A.J.; White, G.L.; Breen, S.L.; Britton, T.; Brooks, K.J.; Green, J.A.; Harvey-Smith, L.; Hindson, L.; Indermuehle, B.; Jones, P.A.; Lowe, V.; Phillips, C.J.; Urquhart, J.S.; Voronkov, M.A.; Whiting, M.T.; Burton, M.G.; Cunningham, M.R.; Lowe, V.; Hindson, L.; Thompson, Mark; Hoare, M.G.; Purcell, C.R.; Jones, P.A.; Longmore, S.N.; Lo, N. (2011-09-01)
      We present first results of the HO Southern Galactic Plane Survey (HOPS), using the Mopra Radio Telescope with a broad-band backend and a beam size of about 2 arcmin. We have observed 100 deg of the southern Galactic plane ...

    • The JCMT Plane Survey : First complete data release - emission maps and compact source catalogue 

      Eden, D.~J.; Moore, T. J. T.; Plume, R.; Urquhart, J.S.; Thompson, M. A.; Parsons, H.; Dempsey, J. T.; Rigby, A.~J.; Morgan, L. K.; Thomas, H. S.; Berry, D J; Buckle, J.; Brunt, Christopher M.; Butner, H. M.; Carretero, D.; Chrysostomou, A.; Currie, M. J.; deVilliers, H.~M.; Fich, M.; Gibb, A. G.; Hoare, M.G.; Jenness, T.; Manser, G.; Mottram, J.~C.; Natario, C.; Olguin, F.; Peretto, N.; Pestalozzi, M.; Polychroni, D.; Redman, R.~O.; Salji, C.; Summers, L.~J.; Tahani, K.; Traficante, A.; diFrancesco, J.; Evans, A.; Fuller, G. A.; Johnstone, D.; Joncas, G.; Longmore, S.~N.; Martin, Gary P; Richer, J. S.; Weferling, B.; White, Glenn J.; Zhu, M. (2017-08-01)
      We present the first data release of the James Clerk Maxwell Telescope (JCMT) Plane Survey (JPS), the JPS Public Release 1 (JPSPR1). JPS is an 850-um continuum survey of six fields in the northern inner Galactic Plane in ...

    • Observational study of sites of triggered star formation - CO and mid-infrared observations 

      Urquhart, J.S.; Morgan, L.K.; Thompson, M.A. (2009)
      Context. Bright-rimmed clouds (BRCs) are isolated molecular clouds located on the edges of evolved HII regions. Star formation within these clouds may have been triggered through the propagation of photoionisation-induced ...

    • A radio and mid-infrared survey of northern bright-rimmed clouds 

      Morgan, L.K.; Thompson, M.A.; Urquhart, J.S.; White, G.J.; Miao, J. (2004)

    • Radio continuum and molecular line observations of four bright-rimmed clouds 

      Urquhart, J.S.; Thompson, M.A.; Morgan, L.K.; White, G.J. (2006)

    • The RMS survey : Galactic distribution of massive star formation 

      Urquhart, J.S.; Figura, C.C.; Moore, T. J. T.; Hoare, M.G.; Lumsden, S. L.; Mottram, J.C.; Thompson, Mark; Oudmaijer, R.D. (2013-11)
      We have used the well-selected sample of~1750 embedded, young, massive stars identified by the Red MSX Source (RMS) survey to investigate the Galactic distribution of recent massive star formation. We present molecular ...

    • A SCUBA survey of bright-rimmed clouds 

      Morgan, L.K.; Thompson, M.A.; Urquhart, J.S.; White, G.J. (2008-01-01)
      Context. Bright-rimmed clouds (BRCs) are potential examples of triggered star formation regions, in which photoionisation driven shocks caused by the expansion of HII regions induce protostellar collapse within the clouds. ...

    • The SCUBA-2 Ambitious Sky Survey: a catalogue of beam-sized sources in the Galactic longitude range 120deg-140deg 

      Nettke, W.; Scott, D.; Gibb, A. G.; Thompson, M.; Chrysostomou, A.; Evans, A.; Hill, T.; Jenness, T.; Joncas, G.; Moore, T.; Serjeant, S.; Urquhart, J.S.; Vaccari, M.; Weferling, B.; White, G.; Zhu, M. (2017-06-01)
      The SCUBA-2 Ambitious Sky Survey (SASSy) is composed of shallow 850-µm imaging using the Submillimetre Common-User Bolometer Array 2 (SCUBA-2) on the James Clerk Maxwell Telescope. Here we describe the extraction of a ...

    • Star formation in Galactic spiral arms and the interarm regions 

      Eden, D.J.; Moore, T.J.T.; Morgan, L.K.; Thompson, M.A.; Urquhart, J.S. (2013-05-11)
      The line of sight through the Galactic plane between longitudes l = 37deg.83 and 42deg.50 allows for the separation of Galactic Ring Survey molecular clouds into those that fall within the spiral arms and those located in ...

    • The statistics of triggered star formation : an overdensity of massive young stellar objects around Spitzer bubbles
