    • Can non-ideal magnetohydrodynamics solve the magnetic braking catastrophe? 

      Wurster, J.; Price, Daniel J.; Bate, Matthew R. (2016-03-21) - Journal article
      We investigate whether or not the low ionization fractions in molecular cloud cores can solve the ‘magnetic braking catastrophe’, where magnetic fields prevent the formation of circumstellar discs around young stars. We ...
    • Comparing simulations of AGN feedback 

      Richardson, Mark L. A.; Scannapieco, E.; Devriendt, J.; Slyz, A.; Thacker, Robert J.; Dubois, Y.; Wurster, J.; Silk, J. (2016-07-10) - Journal article
      We perform adaptive mesh refinement (AMR) and smoothed particle hydrodynamics (SPH) cosmological zoom simulations of a region around a forming galaxy cluster, comparing the ability of the methods to handle successively ...
    • Diamonds and the Mantle Geodynamics of Carbon 

      Shirey, Steve; Smit, Karen; Pearson, D Graham; Walter, Michael; Aulbach, Sonja; Brenker, Frank; Bureau, Hélène; Burnham, Antony; Cartigny, Pierre; Chacko, Thomas; Frost , Daniel; Hauri, Erik; Jacob, Dorrit; Jacobsen, Steven; Kohn, Simon; Luth, Robert; Mikhail, Sami; Navon, Oded; Nestola, Fabrizio; Nimis, Paolo; Palot, Mederic; Smith, Evan; Stachel, Thomas; Stagno, Vincenzo; Steele, Andrew; Stern, Richard; Thomassot, Emilie; Thomson, Andrew; Weiss, Yaakov (Cambridge University Press, 2019-10) - Book item
      The science of studying diamond inclusions for understanding Earth history has developed significantly over the past decades, with new instrumentation and techniques applied to diamond sample archives revealing the stories ...
    • On the damping rate of phase-mixed Alfvén waves 

      Prokopyszyn, Alexander Philip Kofi; Hood, Alan William (2019-10-21) - Journal article
      Context. This paper investigates the effectiveness of phase mixing as a coronal heating mechanism. A key quantity is the wave damping rate, γ, defined as the ratio of the heating rate to the wave energy. Aims. This paper ...
    • The context-variable self and autonomy : exploring surveillance experience, (mis)recognition, and action at airport security checkpoints 

      McNamara, Meghan E.; Reicher, Stephen D. (2019-10-22) - Journal article
      This paper critiques and extends the notion of autonomy by examining how common autonomy definitions construct selfhood, with the support of an analysis of airport surveillance experiences. In psychology, autonomy is 1) ...
