(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, 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, 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, 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, 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, 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 ...
-
(Halifax, N.S. : Saint Mary's University, 2009)In this work, we set out to test the feasibility and limitations of using the 1.6[mu]m bump as a photometric redshift indicator and selection technique using publicly available Spitzer/IRAC images in the GOODS fields. We ...
-
(Halifax, N.S. : Saint Mary's University, 2023-08-01)In this work, we examine the application of the wavelet transform to the X-ray timing analyses of active galactic nuclei (AGN) and quasi-periodic eruption sources (QPEs). We find that the power spectral density (PSD) slope ...
-
(Halifax, N.S. : Saint Mary's University, 2021)X-ray emission from Seyfert 1 galaxies has a debated origin. The primary X-ray source is the compact corona, but the secondary X-ray emission is thought to originate from either a Comptonising layer or blurred reflection ...
