  • Flux emergence within mature solar active regions 

    MacTaggart, David (EDP Sciences, 2011-07)
    Aims. Recent insterest in flux emergence within mature active regions has led to several observational studies. Our aim is to model such a scenario and investigate the evolution of the system. Methods. We solve the 3D ...
  • The magnetic structure of surges in small-scale emerging flux regions 

    MacTaggart, David; Guglielmino, S. L.; Haynes, A. L.; Simitev, R.; Zuccarello, F. (EDP Sciences, 2015-03-13)
    Aims. We investigate the relationship between surges and magnetic reconnection during the emergence of small-scale active regions. In particular, to examine how the large-scale geometry of the magnetic field, shaped by ...
  • On magnetic reconnection and flux rope topology in solar flux emergence 

    MacTaggart, David; Haynes, A. L. (Oxford University Press, 2014-02-21)
    We present an analysis of the formation of atmospheric flux ropes in a magnetohydrodynamic solar flux emergence simulation. The simulation domain ranges from the top of the solar interior to the low corona. A twisted magnetic ...
  • On the periodicity of oscillatory reconnection 

    McLaughlin, James A.; Thurgood, John O.; MacTaggart, David (EDP Sciences, 2012-10-31)
    Context. Oscillatory reconnection is a time-dependent magnetic reconnection mechanism that naturally produces periodic outputs from aperiodic drivers. Aims. This paper aims to quantify and measure the periodic nature of ...
