Clustering and dark matter halos of ultra-massive passively evolving galaxies and passive galaxy groups at z ~ 1.6

Cheema, Gurpreet (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] ...
Multimass modelling of milky way globular clusters and implications on their dark remnant content and stellar initial mass function

Dickson, Nolan Marcus (Halifax, N.S. : Saint Mary's University, 2022-08-25)

The distribution of stars and stellar remnants within globular clusters holds clues about their formation and long-term evolution. In this work, we infer best-fitting multimass models for a number of Milky Way globular ...
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) ...
Photometric decomposition of NGC 6166

Blake, Ronald Melvin (Halifax, N.S. : Saint Mary's University, 1996)

We have used CFHT observations in Cousins B and R to probe the structure of the supergiant elliptical galaxy NGC 6166 in Abell 2199. We utilize the isophotal and aperture photometry of nuclei B and C to search for evidence ...
Spectroscopic and structural properties of galaxies in a cluster environment 5.3 billion years ago

Ridgeway, George E.A. (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 ...
