(Halifax, N.S. : Saint Mary's University, 2015)Numerical modeling of active galactic nuclei (AGN) poses many challenges, from uncertainties about the underlying physics to dynamic range issues. We present a study of simulated activity functions (AF; the differential ...
-
(Halifax, N.S. : Saint Mary's University, 1996)The mixing length parameter is a free parameter governing convective energy transport in current stellar models, and is poorly constrained by current photometric observations. Theoretical nonradial pulsation spectra have ...
-
(Halifax, N.S. : Saint Mary's University, 1999)The three supernova remnants, 3C391, W28 and W44, are known to be interacting with their environmental molecular clouds. Our goal in studying such interactions is to determine whether compression by supernova shocks triggers ...

Spectroscopic and structural properties of galaxies in a cluster environment 5.3 billion years ago (Halifax, N.S. : Saint Mary's University, 2023-08-09)We study how environment affects the structural and spectroscopic properties of galaxies in a massive merging cluster at ζ = 0.53. We obtain follow up spectroscopic observations of the cluster, originally identified ...
-
(Halifax, N.S. : Saint Mary's University, 2011)In this work we use the latest results from the four Deep Fields of the Canada France Hawaii Telescope Legacy Survey (CFHTLS) combined with the WIRCam Deep Survey (WIRDs) covering 2 .51 deg [superscript 2] to study the ...
-
(Halifax, N.S. : Saint Mary's University, 2013)A search for relativistically blurred Fe-L [alpha] is performed on 353 nearby broad and narrow line Type-1 active galactic nuclei (AGN). Simple phenomenological modeling is applied to establish the presence of Fe-L[alpha] ...
-
(Halifax, N.S. : Saint Mary's University, 2001)We study the evolution of linear density perturbations in a cosmological background described by scalar-tensor theories (STT) of gravity. The evolution of the density contrast δ is obtained using the Jeans formalism for ...
-
(Halifax, N.S. : Saint Mary's University, 1979)The surface brightness profiles of a sample of supergiant and elliptical galaxies were studied. The original data were gathered by Dr. G.A. Welch, who also wrote the program (PROFIL) for the data reduction.
This ...
-
(Halifax, N.S. : Saint Mary's University, 1996)Surface photometry in B and R is presented for seven brightest cluster galaxies (BCGs) in poor clusters. The primary goal was to detect diffuse envelopes around the BCGs to determine if they are genuine cD galaxies, which ...
-
(Halifax, N.S. : Saint Mary's University, 1990)This thesis presents independently calibrated CCD surface photometry derived from 12 images of the shell galaxy NGC 2865 in the B, V, and R passbands. Short exposures were used to permit accurate sky subtraction. Mean ...
-
(Halifax, N.S. : Saint Mary's University, 2023-08-11)Part of our understanding of how galaxies evolve is based on individual evolutions inferred from population trends. In its strictest form, this approach implicitly assumes that the star formation properties of galaxies ...
-
(Halifax, N.S. : Saint Mary's University, 2005)The nearly edge---on S0 galaxy NGC 5866 is notable for its massive molecular interstellar medium, prominent central dust lane, and large IRAS 100 micron flux. The galaxy is relatively isolated, and neither the kinematics ...
-
(Halifax, N.S. : Saint Mary's University, 2007)NGC 2024 is a star-forming region in Orion B which contains a dense molecular ridge and a number of dense cores seen by their dust emission (Mezger et al., 1992). This area is investigated using observations of four ...
-
(Halifax, N.S. : Saint Mary's University, 1985)A systematic procedure for processing and reducing CCD-generated images has been developed. It involves removing unwanted objects and blemishes, subtracting the bias offset, removing the thermal background; correcting for ...
-
(Halifax, N.S. : Saint Mary's University, 1998)In this study we attempt to discover, using data taken by Bernstein et al. (1995, Bea95), whether there exists a population of intracluster globular clusters (IGC) within the core of the Coma Cluster of Galaxies. Models ...
-
(Halifax, N.S. : Saint Mary's University, 1977)At the suggestion of Dr. D.L. DuPuy, the young open clusters of NGC 6604 and NGC 6704 were observed in the UBV wide-band system in order to obtain improved colour-magnitude diagrams and estimates of distance. A short ...
-
(Halifax, N.S. : Saint Mary's University, 1993)In this thesis, the nature of the star forming core of the Mon R2 cloud is investigated using new, high spatial resolution observations. The new data include: maps of [superscript 12]CO J=3[right arrow]2, HCN J=4[right ...
-
(Halifax, N.S. : Saint Mary's University, 1988)This thesis presents a stellar space density analysis in the galactic plane at l = 268 [degree sign]. The data consist of photographic UBV photometry for 2461 stars and MK spectral classifications for 1713 of these. A ...

(Halifax, N.S. : Saint Mary's University, 1979)The surface brightness profiles of a sample of supergiant and elliptical galaxies were studied. The original data were gathered by Dr. G.A. Welch, who also wrote the program (PROFIL) for the data reduction. This study ...
-
(Halifax, N.S. : Saint Mary's University, 2013)We present a grid of line blanketed spherical LTE model atmospheres and high resolution extinction spectra for use in interpolating an accurate outer boundary condition for asteroseismology calculations at arbitrary ...
