    • Circular polarization of synchrotron radiation in high magnetic fields 

      de Burca, Diarmaid; Shearer, Andrew (Oxford University Press, 2015-04-17)
      The general model for incoherent synchrotron radiation has long been known, with the first theory being published by Westfold in 1959 and continued by Westfold and Legg in 1968. When this model was first developed, it was ...

    • Exceptionally bright TEV flares from the binary LS I+61 degrees 303 

      Connolly, M.P.; Gillanders, Gary; Lang, Mark (IOP Publishing, 2016-01-20)
      The TeV binary system LS I +61 degrees 303 is known for its regular, non-thermal emission pattern that traces the orbital period of the compact object in its 26.5 day orbit around its B0 Ve star companion. The system ...

    • The Galway astronomical Stokes polarimeter: an all-Stokes optical polarimeter with ultra-high time resolution 

      Collins, Patrick; Kyne, Gillian; Lara, David; Redfern, Michael; Shearer, Andrew; Sheehan, Brendan (Springer Verlag, 2013-06-28)
      Many astronomical objects emit polarised light, which can give information both about their source mechanisms, and about (scattering) geometry in their source regions. To date (mostly) only the linearly polarised components ...

    • Gamma-rays from the quasar PKS 1441+25: story of an escape 

      Connolly, M.P.; Gillanders, Gary; Lang, Mark (2015-12-20)
      Outbursts from gamma-ray quasars provide insights on the relativistic jets of active galactic nuclei and constraints on the diffuse radiation fields that fill the universe. The detection of significant emission above 100 ...
