    • Figure rotation of dark haloes in cold dark matter simulations 

      Bryan, Scott E.; Cress, Christine M (Oxford University Press, 2007)
      We investigate the figure rotation of dark matter haloes identified in cold dark matter (CDM) simulations.We find that when strict criteria are used to select suitable haloes for study, five of the 222 haloes identified ...

    • MIGHTEE-Hi: The relation between the Hi gas in galaxies and the cosmic web 

      Tudorache, Madalina N.; Jarvis, Matthew J.; Heywood, Ian (Oxford University Press, 2022)
      We study the 3D axis of rotation (3D spin) of 77 Hi galaxies from the MIGHTEE-Hi Early Science observations, and its relation to the filaments of the cosmic web. For this Hi-selected sample, the alignment between the spin ...

    • A new technique to isolate kinematically anomalous gas in HI data cubes 

      Randriamiarinarivo, N; Elson, E. C.; Baker, A. J. (Oxford University Press, 2023)
      H I line observations of nearby galaxies often reveal the presence of extraplanar and/or kinematically anomalous gas that deviates from the general circular flow. In this work, we study the dependence of kinematically ...
