Analysing and predicting chaos from shocks and radiative cooling in simulations of cosmic structure formation

Mungara, Paresh (Halifax, N.S. : Saint Mary's University, 2020)

It has long been appreciated that galaxy formation involves physics that can be subject to chaos. Numerical simulations introduce an additional source of noise in the form of approximations and floating point arithmetic ...
Blue BX galaxies breaking bad : allegations of a 2175Å feature at z ~ 2.2 in violation of the Calzetti dust law

Golob, Anneya (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 ...
Contour advection tracer method in smoothed particle hydrodynamics

Fields, Tiffany M. (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 ...
Evolution of galaxy morphology in the field and cluster environment since z ∼ 1

George, Angelo (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_∗
The evolution of star formation rates in high-redshift galaxies

Marquis, Andrew H. (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 ...
Investigating the impact of stellar feedback algorithms on galactic evolution

Pillsworth, Samantha R. (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 ...
Number density distribution of satellite galaxies around massive central galaxies in CLAUDS + HSC at 0.3 < z < 0.9

Chen, Lingjian (Halifax, N.S. : Saint Mary's University, 2019)

Satellite galaxies around massive central galaxies can provide important information about galactic environmental effect. In this thesis, we selected thousands of massive (log(M_cen/M_☉) > 11.15) ...
PHIBSS fibs : a SCUBA2 followup of z ~ 2.5, gas-rich, star forming galaxies

Beanlands, Jennifer K. (Halifax, N.S. : Saint Mary's University, 2015)

Emissions from high redshift (i.e. z ~ 2.5), star forming galaxies provide a unique window into the state the universe at earlier epochs, and how these galaxies evolve over time. Accurate studies of these galaxies, however, ...
Star-forming and passive galaxies at z ~ 2 in the CFHT Legacy Survey

Arcila-Osejo, Liz María (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 ...
Using the 1.6[mu]m bump to study rest-frame H-band selected galaxies at redshift 2

Sorba, Robert (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 ...
