Advancing Techniques for Detecting Dwarf Satellite Populations Beyond the Local Group
(University of Waterloo, 2022-05-20)This thesis includes material from three papers that develop techniques for quantifying faint dwarf satellite populations outside the Local Group. Dwarf satellites are important for our understanding of small-scale structure ... -
Galaxy Morphology In Cluster Environments
(University of Waterloo, 2017-08-25)It is a well known fact that cluster environments favour early-type galaxies over late- type. However, the physical origin of the correlation remains uncertain. We focus specifically on the external environmental mechanisms ... -
Messier 87: A Laboratory for Exploring AGN Variability using the Event Horizon Telescope
(University of Waterloo, 2020-09-17)At a distance of 50 million light years at the heart of the Virgo cluster, lies the giant elliptical galaxy Messier 87. This galaxy has at its center a brilliant relativistic jet, observable at all wavelengths, and at the ... -
Probing the Environmental Dependence of Star Formation in Satellite Galaxies using Orbital Kinematics
(University of Waterloo, 2013-09-03)(Abridged) Physical processes regulating star formation in satellite galaxies represent an area of ongoing research, but the projected nature of observed coordinates makes separating different populations of satellites ... -
Star Formation and Quenching in Galaxies: Groups, Clusters, and Mergers
(University of Waterloo, 2023-08-21)This thesis studies the impact of galaxy environment on star formation and ‘quenching’, by using simple physically-motivated models that can be fit using available observed quantities. Quenching refers to the close to total ... -
Tracing galaxy evolution through the reconstruction of their star formation histories
(University of Waterloo, 2023-05-24)This thesis studies the star formation histories (SFHs) of galaxies in order to understand the nature of 'quenching.' The suppression of star formation, i.e., quenching, over the history of the Universe results in a growing ... -
Ultraviolet Sizes and Morphology of Galaxies in the Coma Cluster
(University of Waterloo, 2022-08-25)We present a study of the Coma cluster using ultraviolet (UV) imaging obtained using the Ultraviolet Imaging Telescope. We discuss methods for measuring sizes and morphology of galaxies in the UV. Several cluster galaxies ...
