Gravitational Lensing in the Solar Neighbourhood and Towards the Milky Way Bulge
(2022-01-29)This thesis is concerned with looking for and characterizing microlensing events in two places that are relatively unexplored. Leveraging astrometry from the Gaia satellite, I search for predicted close stellar alignments ... -
The effect of bombardment of small bodies on the evolution of atmospheres of terrestrial bodies
The atmospheres of bodies in the Solar system display a great degree of diversity in their mass and composition. Impacts onto these bodies by smaller objects, such as asteroids, comets and planetesimals left over after ... -
Black Hole Feedback in New Regimes: Modelling Dwarf Galaxies with Active Galactic Nuclei
Contrary to the standard lore, there is mounting observational evidence that feedback from active galactic nuclei (AGN) may also play a role at the low-mass end of the galaxy population. In this thesis, I explore that ... -
QSO Absorption Lines
(1987-02-26)The absorption lines found in the spectra of distant quasars provide a unique method of probing the physical conditions in the universe at early epochs. This thesis describes a study of the Lyman alpha forest absorption ...
