    • Can Lensing Measure The Shape Of Dark Matter Halos? 

      Hussain, Uzair (University of Waterloo, 2012-09-27)
      The aim of this project was to explore the shapes of dark matter halos using high resolution N-body simulations. One of the main aspects explored was how well the shape can be measured through weak lensing. To explore this, ...
    • The Dependence of Halo Mass on Galaxy Size at Fixed Stellar Mass Using Weak Lensing 

      Charlton, Paul (University of Waterloo, 2017-04-24)
      Stellar mass has been shown to correlate with halo mass, but with significant scatter. The stellar mass-size and luminosity-size relationships of galaxies also show significant scatter in galaxy sizes for a fixed stellar ...
    • Emergence and Phenomenology in Quantum Gravity 

      Premont-Schwarz, Isabeau (University of Waterloo, 2010-07-09)
      In this thesis we investigate two approaches to quantum gravity. The first is the emergence of gravity from a discrete fundamental theory, and the second is the direct quantisation of gravity. For the first we develop tools ...
    • The Evolution of Dark Matter Haloes in Mergers 

      Drakos, Nicole (University of Waterloo, 2019-08-22)
      In the standard Λ-cold dark matter (ΛCDM) cosmological model, the present-day universe contains dominant components of dark energy (Λ) and cold dark matter (CDM). Fluctuations in the initial distribution of dark matter ...
    • An Exploration of Clustering Statistics and Tidal Alignments in the Context of Group Catalogues 

      De Marchi, Nick (University of Waterloo, 2021-10-04)
      The use of three-dimensional galaxy surveys and large cosmological simulations of the galaxy distribution has advanced our understanding of large-scale structure over the last few decades. At the forefront of this are ...
    • The Shape of Dark Matter Haloes: Results from Weak Lensing 

      Robison, Bailey (University of Waterloo, 2020-09-25)
      Dark matter haloes are expected to have a triaxial shape, appearing elliptical in projection. Understanding the orientation of these dark matter haloes, and how they are aligned, has implications for theories of structure ...
