    • Maser radiation from collisionless shocks 

      Speirs, D. C.; Ronald, K.; Phelps, A. D. R.; Koepke, M. E.; Cairns, Robert Alan; Rigby, A.; Cruz, F.; Trines, R. M. G. M.; Bamford, R.; Kellet, B. J.; Albertazzi, B.; Cross, J. E.; Fraschetti, F.; Graham, P.; Kozlowski, P. M.; Kuramitsu, Y.; Miniati, F.; Morita, T.; Oliver, M.; Reville, B.; Sakawa, Y.; Sarkar, S.; Spindloe, C.; Koenig, M.; Silva, L. O.; Lamb, D. Q.; Tzeferacos, P.; Lebedev, S.; Gregori, G.; Bingham, R. (2019) - Journal article
      This paper describes a model of electron energization and cyclotron-maser emission applicable to astrophysical magnetized collisionless shocks. It is motivated by the work of Begelman, Ergun and Rees [Astrophys. J. 625 , ...
    • Computational approaches and analysis for a spatio-structural-temporal invasive carcinoma model 

      Hodgkinson, Arran; Chaplain, Mark Andrew Joseph; Domschke, Pia; Trucu, Dumitru (2018-04) - Journal article
      Spatio-temporal models have long been used to describe biological systems of cancer, but it has not been until very recently that increased attention has been paid to structural dynamics of the interaction between cancer ...
    • Robustness of vortex populations in the two-dimensional inverse energy cascade 

      Burgess, Belle Helen; Scott, Richard Kirkness (2018-09-10) - Journal article
      We study how the properties of forcing and dissipation affect the scaling behaviour of the vortex population in the two-dimensional turbulent inverse energy cascade. When the flow is forced at scales intermediate between ...
    • The merger of geophysical vortices at finite Rossby and Froude number 

      Reinaud, Jean N.; Dritschel, David G. (2018-08-10) - Journal article
      We investigate the merger of two co-rotating geophysical vortices at finite Rossby and Froude number.  The initial conditions consist of two uniform potential vorticity vortices in near equilibrium and in a near 'balanced' ...
    • The interaction of two co-rotating quasi-geostrophic vortices in the vicinity of a surface buoyancy filament 

      Reinaud, Jean Noel (2018) - Journal article
      In this paper, we investigate the interaction between two like-signed quasi-geostrophic uniform potential vorticity internal vortices in the vicinity of a surface buoyancy anomaly filament in a three dimensional, stably ...
