Galaxy Transformations in the Last 5 Billion Years
(University of Waterloo, 2010-09-01)It has become clear that the global star formation rate in the Universe has been decreasing since at least z~1, and blue, star-forming galaxies are transformed into red, passive galaxies through one or more processes. The ... -
Hunting for the Primordial Quenched Population in 2 < z < 2.5 COSMOS Protoclusters
(University of Waterloo, 2024-01-17)We present an analysis of the galaxy stellar mass function (SMF) of 14 known protoclusters between 2.0 < z < 2.5 in the COSMOS field, down to a mass limit of 10⁹ᐧ⁵ M⊙. We use existing photometric redshifts with a statistical ... -
Testing the Extremes of Initial Mass Function Variability using Compact Stellar Systems
(University of Waterloo, 2022-07-29)The initial mass function (IMF) is a cornerstone in star formation and galaxy evolution studies. It has traditionally been assumed to be universal, but this has been challenged by increasingly detailed observations of ... -
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 ...
