    • The bivariate space density of galaxies 

      Cross, Nicholas James Geraint (University of St Andrews, 2002) - Thesis
      The luminosity function of galaxies, the measurement of the space density as a function of luminosity, is an important test of cosmology, galaxy formation and evolution. Unfortunately, there is a factor of two variation ...

      Kelvin, Lee Steven (University of St Andrews, 2013-06-26) - Thesis
      The mechanisms which cause galaxies to form and evolve each leave behind distinct structural markers in their wake. Dynamically hot processes (e.g., monolithic collapse, hierarchical merging) give rise to pressure-supported ...
