    A study of the double galaxy in Abell Cluster 1775 
    Hayes, Jeffrey J. E.(Jeffrey John Edward),1957- (Halifax, N.S. : Saint Mary's University, 1981)
    Photographic and photoelectric photometry are used to obtain intensity profiles of the A1775 double galaxy. The intensity profiles are fitted to the standard (c = 2.25) King models, from which composite models are constructed. ...

    Core radii determinations for four clusters of galaxies 
    Calnan, Colin,1953- (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, ...

    The origin and evolution of cold gaseous structures in galaxies and galactic outflows 
    Williamson, David John (Halifax, N.S. : Saint Mary's University, 2013 [i.e. 2012]., 2012)
    This thesis examines the formation and evolution of cold gaseous structures in galaxies and galactic outflows in two distinct scenarios. Previous analytic estimates of the viscous time-scale due to cloud-cloud collisions ...

    Probing the interstellar medium of high-redshift sub-millimetre and emission line galaxies 
    Cunningham, Daniel J. M. (Halifax, N.S. : Saint Mary's University, 2018)
    Utilizing new ALMA-ACA observations of the [N II] 205 µm line in combination with existing [C II] 158 µm observations, we characterize the L[C II]/L[N II] distribution in highredshift ...

    The surface brightness profiles of elliptical and supergiant galaxies 
    English, Darlene 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 ...

    Using model spectral energy distributions to study galaxy masses : now and in the future 
    Sorba, Robert (Halifax, N.S. : Saint Mary's University, 2017)
    The determination of galaxy masses is an essential tool for our understanding of galaxy evolution. Looking at 67 local galaxies, we find that galaxy stellar masses are underestimated using traditional methods that assume ...
