  • Accelerating reionization simulations using machine learning 

    Masipa, Mosima Portia (University of the Western Cape, 2023)
    Epoch of Reionization (EoR) refers to the time in the history of the universe when the appearance of the first luminous sources reionized the intergalactic medium (IGM). The EoR carries a wealth of information regarding ...
  • The nature of the microjy source population 

    Ocran Emmanuel Francis (University of the Western Cape, 2015)
    The study of the faint radio universe and of its properties has recently become a very active field of research not only because of the much improved capabilities of the SKA pathfinders but also because of the need to ...
  • Reconstruction of the ionization history from 21cm maps with deep learning 

    Mangena (University of the Western Cape, 2020)
    Upcoming and ongoing 21cm surveys, such as the Square Kilometre Array (SKA), Hydrogen Epoch of Reionization Array (HERA) and Low Frequency Array (LOFAR), will enable imaging of the neutral hydrogen distribution on ...
  • Testing gravity with redshift-space distortions, using MeerKAT and the SKA 

    Viljoen, Jan-Albert (University of the Western Cape, 2019)
    The growth rate of large-scale structure is a key probe of gravity in the accelerating Universe. Standard models of Dark Energy within General Relativity predict essentially the same growth rate, whereas Modified Gravity ...
