(Halifax, N.S. : Saint Mary's University, 2007)We investigate in detail the potential of asteroseismology in exploring the structure of intermediate mass (1.6 ≤ M⊙ ≤ 5.0) pre-main sequence stars. It is expected that pre- and post-main sequence ...
-
(Halifax, N.S. : Saint Mary's University, 2018)Using a sample of galaxies (M⋆ ≥ 1010.5M⊙) covering an effective area of ∼ 20 deg2 in the CLAUDS+HSC survey, we apply a Random Forest Classifier to automatically identify merger ...
-
(Halifax, N.S. : Saint Mary's University, 2013)The dust properties of star forming galaxies at z ~ 2 are examined using a sample of BX objects selected from the Keck Deep Fields (KDF) using colour-colour selection criteria. Spectral energy distribution (SED) fitting ...
-
(Halifax, N.S. : Saint Mary's University, 2008)The standard paradigm for radio galaxies is based on high-speed plasma jets, formed in active galactic nuclei, which then penetrate into the surrounding inter-galactic medium creating giant lobes of luminous material. These ...
-
(Halifax, N.S. : Saint Mary's University, 1978)The MK classification system is defined by the spectra of an array of standard stars and is based on the appearances and relative intensities of selected spectral lines, blends, and bands observed in the blue-violet ...
-
(Halifax, N.S. : Saint Mary's University, 2017)Using a sample of gzK selected passive galaxies at z ~ 1.6 covering an effective area of 27 deg[superscript 2], we used the clustering measurements of Ultra Massive Passively Evolving Galaxies (UMPEGs, M[subscript stellar] ...
-
(Halifax, N.S. : Saint Mary's University, 2019)Studying the evolution of galaxies is important in understanding many other astrophysical phenomenon. However, this process required numerical work due to long timescales over which evolution occurs. To study the effects ...
-
(Halifax, N.S. : Saint Mary's University, 1979)Bahcall (1975) has found that the average core radius for a group of 15 clusters of galaxies is 0.25[plus or minus]0.05 Mpc. At the suggestion of Dr. G. Welch it was decided to study four nearby clusters of galaxies (A2052, ...
-
(Halifax, N.S. : Saint Mary's University, 2013)This work presents a deep analysis of HE 0436-4717: a “bare” Seyfert 1 galaxy with strong variability and moderate soft excess. Data included a 200 ks observation with XMM-Newton EPIC instruments, a Swift BAT detection up ...
-
(Halifax, N.S. : Saint Mary's University, 2011)The XMM-Newton Observatory has conducted many observations of the type I active galactic nucleus 1H0707-495. The 0.7 deg [superscript 2] field of view around the AGN was observed over the course of ∼10 years with a total ...
-
(Halifax, N.S. : Saint Mary's University, 1998)Observational evidence and theoretical arguments indicate that most of the universe is made of dark matter. Supersymmetry, an extension of the standard model of particle interactions, provides a natural candidate for dark ...
-
(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. ...
