Gas in Void Galaxies
Void galaxies, residing within the deepest underdensities of the Cosmic Web, present an ideal population for the study of galaxy formation and evolution in an environment undisturbed by the complex processes modifying galaxies in clusters and groups, and provide an observational test for theories …

Comparing Simulations and Observations of Galaxy Evolution: Methods for Constraining the Nature of Stellar Feedback
… are a very useful tool for understanding how galaxies form and evolve over cosmological timescales not easily revealed through observations. However, they are only useful if they reproduce the sorts of galaxies that we see in the real universe. One of the ways in which simulations of this sort …

Properties of Galaxies Detected in Emission and Absorption with Background Quasars
<p>The question of how galaxies evolve is a difficult one to answer. By studying galaxies hosting Damped (DLA) and sub-Damped Lyman-alpha (sub-DLA) systems, we hope to shed some light on the subject. DLA and sub-DLA systems contain the vast majority of neutral gas in the universe, making them ideal …

The Universality of Intrinsic Flattening in Extragalactic Stellar Disks
Highly inclined (edge-on) galaxies provide the unique perspective necessary to constrain the intrinsic flattening, 𝑐/𝑎, of galactic disks. We use “dust-free” 3.6 𝜇m maps of 141 edge-on spiral galaxies from the Spitzer Survey of Stellar Structure in Galaxies (S4G) and its early-type galaxy extension …

Star-forming Galaxies and Quenched Systems throughout Cosmic Time
… delves into the investigation of star-forming galaxies and quenched systems at high redshifts, exploring their evolution and properties throughout cosmic time. Firstly, I utilise the foreground lensing of massive galaxy clusters in the Hubble Frontier Fields to probe the high-redshift evolution …
