    • Very High Energy Observations of Gamma-Ray Burst Locations with the Whipple Telescope 

      Lang, Mark; Gillanders, Gary (2007)
      Gamma-ray burst (GRB) observations at very high energies (VHE, E > 100 GeV) can impose tight constraints on some GRB emission models. Many GRB afterglow models predict a VHE component similar to that seen in blazars and ...

    • VLT / Infrared Integral Field Spectrometer Observations of Molecular Hydrogen Lines in the Knots in the Planetary Nebula NGC 7293 (the Helix Nebula) 

      Redman, Matt P. (2007)
      Knots are commonly found in nearby planetary nebulae (PNe) and star forming regions. Within PNe, knots are often found to be associated with the brightest parts of the nebulae and understanding the physics involved in knots ...

    • VLT polarimetry observations of the middle-aged pulsar PSR B0656+14 

      Moran, Paul; Shearer, Andrew (EDP Sciences, 2015-11-02)
      Context. Optical polarisation measurements are key tests for different models of the pulsar magnetosphere. Furthermore, comparing the relative orientation of the phase-averaged linear polarisation direction and the pulsar ...

    • Volcanic sulphate and arctic dust plumes over the North Atlantic Ocean 

      Ovadnevaite, Jurgita; Ceburnis, Darius; Dupuy, Regis; Berresheim, Harald; O Dowd, Colin D. (Elsevier, 2009)
      High time resolution aerosol mass spectrometry measurements were conducted during a field campaign at Mace Head Research Station, Ireland, in June 2007. Observations on one particular day of the campaign clearly indicated ...

    • Whitecaps and the marine atmosphere, report no. 3 

      Spillane, M. C.; O'Muircheartalgh, I.G.; Monahan, E.C. (1981-04)
      This report covers the period from 1 July, 1980 to 31 March, 1981, and is devoted to a description of the work carried out, and the results obtained, during this interval on the on-going ONR-sponsored study of "The Influence ...

    • Whitecaps and the marine atmosphere, report no. 5 

      Monahan, E. C. (1983-06)
      During this year we have continued making measurements of aerosols and electrostatic charge from our coastal tower in Gort na gCapall on Inishmore. Likewise, the experiments centred on the Whitecap Simulation Tank are ...

    • Whitecaps and the marine atmosphere, report no. 6 

      Doyle, David M. (1984-06)
      This study is concerned with the interdependence of 10m elevation wind speed, oceanic whitecap coverage and marine aerosol concentration. The field work is divided into two distinct phases. On Inishmore Co. Galway. ...

    • Whitecaps and the marine atmosphere, report no. 7 

      Monahan, E. C. (1984-10)
      This report describes the general activities and findings of the Whitecap Project in the 16-month-long period 1 June 1983-30 September 1984. Additional results obtained during this period from this study of whitecaps ...

    • Whitecaps and the marine atmosphere, report no. 8 

      Monahan, E. C. (1985-10)
      During the 12-month-long period covered by this report, i.e. in the 1 October 1984 - 30 September interval, all facets of the Whitecap Project progressed apace. The field work during this year included both international and ...
