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 ... -
On The Origin of Cold Molecular Gas In Giant Elliptical Galaxies
(University of Waterloo, 2017-01-23)We present an analysis of 55 giant elliptical galaxies residing in the centre of clusters and groups to investigate the origin of H₂ molecular gas centrally located in these galaxies. Using Chandra X-ray data and IRAM 30m ... -
Powerful Shocks and Cavities in the Hot Atmosphere of the MS 0735 Galaxy Cluster
(University of Waterloo, 2014-08-26)Cool core clusters host bright centres that radiate away their energy in less than 10^9 yr. If uncompensated by heating, the hot atmosphere will cool and form stars at rates of hundreds to thousands of solar masses per ... -
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 ... -
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 ... -
X-ray Astrophysics: The Spoiler Clusters and XRISM Synchrotron Calibrations
(University of Waterloo, 2019-10-22)Cool core galaxy clusters hosting brightest cluster galaxies (BCGs) in their centres radiate away their energy on timescales of less than 10^9 yr. If cooling wasn't offset by some form of heating, the hot atmosphere would ...
