    • 3D pic simulations of collisionless shocks at lunar magnetic anomalies and their role in forming lunar swirls 

      Bamford, R. A.; Alves, E. P.; Cruz, F.; Kellett, B. J.; Fonsesca, R. A.; Silva, L. O.; Trines, R. M. G. M.; Halekas, J. S.; Kamer, G.; Harnett, E.; Cairns, Robert Alan; Bingham, R. (2016-10-18) - Journal article
      Investigation of the lunar crustal magnetic anomalies offers a comprehensive long-term data set of observations of small-scale magnetic fields and their interaction with the solar wind. In this paper a review of the ...
    • Can substorm particle acceleration be applied to solar flares? 

      Birn, Joachim; Battaglia, Marina; Fletcher, Lyndsay; Hesse, Michael; Neukirch, Thomas (2017-10-20) - Journal article
      Using test particle studies in the electromagnetic fields of three-dimensional magnetohydrodynamic (MHD) simulations of magnetic reconnection, we study the energization of charged particles in the context of the standard ...
    • Flare particle acceleration in the interaction of twisted coronal flux ropes 

      Threlfall, J.; Hood, A. W.; Browning, P. K. (2018-03-20) - Journal article
      Aims. The aim of this work is to investigate and characterise non-thermal particle behaviour in a three-dimensional (3D) magnetohydrodynamical (MHD) model of unstable multi-threaded flaring coronal loops. Methods.  We have ...
    • Particle acceleration at reconnecting separator current layers 

      Threlfall, J.; E. H. Stevenson, J.; E. Parnell, C.; Neukirch, T. (2016) - Journal article
      The aim of this work is to investigate and characterise particle behaviour in a 3D MHD model of a reconnecting magnetic separator. We use a relativistic guiding-centre test-particle code to investigate electron and proton ...
    • Particle dynamics in a non-flaring solar active region model 

      Threlfall, J.; -A. Bourdin, Ph.; Neukirch, T.; E. Parnell, C. (2016-03) - Journal article
      The aim of this work is to investigate and characterise particle behaviour in a (observationally-driven) 3D MHD model of the solar atmosphere above a slowly evolving, non-flaring active region. We use a relativistic ...
    • Particle energisation in a collapsing magnetic trap model : the relativistic regime 

      Eradat Oskoui, S.; Neukirch, T. (2014-07) - Journal article
      Context. In solar flares, a large number of charged particles is accelerated to high energies. By which physical processes this is achieved is one of the main open problems in solar physics. It has been suggested that ...
