Basis Sets in Galactic Dynamics
Since their introduction in 1972 by Clutton-Brock, so-called biorthogonal basis sets have become a popular tool in galactic dynamics. They provide a method of solving Poisson's equation that scales linearly with the number ... -
Galaxy-Scale Signatures of Screened Modified Gravities
(2020-11-28)In recent years, theories of gravity incorporating a scalar field coupled to gravity---'scalar-tensor' theories---have been subject to increased attention. In these theories, the scalar field mediates gravitational-strength ... -
Polluted White Dwarfs: Insights into Ancient Extrasolar Planetary Systems
(2020-09-30)As the study of rocky exo-planets enters an era of characterisation, the ability to determine how similar a planet is to the Earth, and thus if it is potentially habitable, is fast approaching. An understanding of the ... -
Understanding the Epoch of Reionization Using Simulations of Lyman-α Emitting Galaxies and 21-cm Emission
This thesis covers three projects, all centred around using computational simulations to theoretically model the intergalactic medium (IGM) and Lyman-α emitting (LAE) galaxies in the early universe. These galaxies are a ...
