(Halifax, N.S. : Saint Mary's University, 2013)The ISAC charged particle reaction spectroscopy station (IRIS), a new experimental facility at TRIUMF, is developed to study light and heavy proton- and neutron-rich nuclei. Due to the production processes of these nuclei, ...
-
(Halifax, N.S. : Saint Mary's University, 2007)It is well established that the broadband colors of elliptical galaxies become redder near their centres, which provides an important constraint on models of elliptical galaxy formation. The observed radial color gradients ...
-
(Halifax, N.S. : Saint Mary's University, 2012)The spectrum of the rapidly rotating star [alpha] Oph was modeled to examine the effect differential rotation has on its observed SED. Rotating stellar structure models were generated using the code ROTORC and constrained ...
-
(Halifax, N.S. : Saint Mary's University, 2007)Models have been produced to study the spectral energy distributions (SEDs) and absorption lines for rapidly rotating B stars. A fully implicit 2D stellar structure and evolution code was used to generate the rotating ...
-
(Halifax, N.S. : Saint Mary's University, 2007)This thesis investigates the effects of stellar rotation on the HR diagram location of members within young clusters. The rotational effects on luminosity and temperature of a star depend on the viewing angle and the ...
-
(Halifax, N.S. : Saint Mary's University, 1993)Existing calibrations of white dwarf luminosities have invariably relied upon the inhomogeneous sample of refractor parallaxes published in the General Catalogue of Trigonometric Parallaxes. We have completed a new calibration ...

(Halifax, N.S. : Saint Mary's University, 2020)The study of galaxy morphology can provide important information about how galaxies evolve. In this thesis, we study size and concentration of light profiles for ∼15000 star-forming galaxies (SFGs, M∗
(Halifax, N.S. : Saint Mary's University, 2010)We use photometric galaxy samples and spectral synthesis models to investigate the ability of three dramatically divergent star formation histories (SFHs) to describe the build-up of stellar mass in galaxy populations ...
(Halifax, N.S. : Saint Mary's University, 2001)Stellar evolution models and their associated non-radial pulsation spectra are presented for the nearby stars [varepsilon] Eridani (K2 V), β Hydri (G2 IV), β Geminorum (K2 III). This analysis was performed in preparation ...
(Halifax, N.S. : Saint Mary's University, 2017)The differences in emissivity profiles produced by various corona geometries are explored via general relativistic ray tracing simulations in order to better understand the inner disc region of active galactic nuclei. ...
(Halifax, N.S. : Saint Mary's University, 1996)We present deep V and R band CCD photometry of the globular cluster systems of Hickson compact group galaxy 22a (NGC 1199) and 90c (NGC 7173), taken with the European Southern Observatory's New Technology Telescope (NTT). ...
(Halifax, N.S. : Saint Mary's University, 2005)Sub-millimetre mapping of Orion B (L1630) using SCUBA on the James Clerk Maxwell Telescope has revealed a large population of compact cores (Mitchell et al. 2001). Using the CFHT-IR camera on the Canada-France-Hawaii ...
(Halifax, N.S. : Saint Mary's University, 2016)The numerical algorithm used to implement stellar feedback in a galactic simulation will strongly influence the resulting disk. Using two disks from the MUGS2 simulation suite (Keller et al., 2015), we study the morphologies ...
(Halifax, N.S. : Saint Mary's University, 2015)We present the first effort to understand the effect of the three-nucleon force on the angular distribution of nucleus-proton scattering near the drip-line. We successfully performed the elastic scattering of the unstable ...
(Halifax, N.S. : Saint Mary's University, 2019)X-ray observations of two Seyfert AGN were analysed in an effort to characterise the nature of their variability. A spectral analysis was performed on a Suzaku observation of the Seyfert 1.5 AGN Mrk 530, and a timing ...
(Halifax, N.S. : Saint Mary's University, 2020)Understanding the structure of complex many-body nuclei is one of the central challenges in nuclear physics. The conventional shell model is capable of explaining the structure of stable nuclei, but it starts to shatter ...
(Halifax, N.S. : Saint Mary's University, 2001)Fritz Zwicky is identified commonly as the discoverer of dark matter, the unobservable mass that is believed to occupy about 90 percent of the universe. In 1933 Zwicky found a mass discrepancy in the Coma cluster of galaxies, ...
(Halifax, N.S. : Saint Mary's University, 2006)Optical coronagraphic imaging of the circumstellar dust disk around β Pictoris reveals that the inner portion of the disk is warped, and this warp is typically attributed to the presence of a planetary system. Mouillet et ...
(Halifax, N.S. : Saint Mary's University, 2005)I investigate the effects of varying internal angular momentum distributions on the SEDs of massive stars. Rapidly rotating stars are deformed by rotation, and the degree of deformation can give us a further constraint on ...
(Halifax, N.S. : Saint Mary's University, 2003)A cooling flow forms in a galaxy cluster when the internal pressure of the gas drops below the gravitational potential of the cluster due to the cooling of the X-ray gas in the Inter-Cluster Medium (ICM). The cooling flow ...
