Southern voids : structure and cosmological implications
A review of standard cosmology theory and observational results is presented. The main tool for investigating large-scale structure in this thesis is a visually compiled void catalogue. Void selection effects that cause the detected distribution of voids to differ from the true distribution are …

Dark Matter Halo Concentration and the Evolution of Spiral Structure in N-Body, Barred Spiral Galaxies
<p>Motivated by the evidence of relationships between pitch angle (the tightness of spiral arm structure in the disk), P, and various indicators of central mass concentration, as well as the theoretical relationship between halo mass concentration and the density of visible matter in the central …

Phase-space reconstructions of cosmic velocities and the cosmic web
In the current paradigm of cosmology, the formation of large-scale structures is mainly driven by non-radiating dark matter, making up the dominant part of the matter budget of the Universe. Cosmological observations however, rely on the detection of luminous galaxies, which are biased tracers of …
