    • Hard spectral tails in magnetars 

      Wadiasingh, Zorawar; Baring, Matthew G.; Gonthier, Peter L.; Harding, Alice K. (Cambridge Univ Press, 2017)
      Pulsed non-thermal quiescent emission between 10 keV and around 150 keV has been observed in ~10 magnetars. For inner magnetospheric models of such hard X-ray signals, resonant Compton upscattering of soft thermal photons ...
    • The millisecond pulsar contribution to the rising positron fraction 

      Venter, Christo; Kopp, Andreas; Büsching, Ingo; Harding, Alice K.; Gonthier, Peter L. (Sissa Medialab, 2016)
      Pair cascades from millisecond pulsars (MSPs) may be a primary source of Galactic electrons and positrons that contribute to the increase in positron flux above 10 GeV as observed by PAMELA and AMS−02. The Fermi Large ...
