Automated detection of merging galaxies at z = 0.25 − 1.0 in the CLAUDS+HSC survey using random forests

Thibert, Nathalie C. M. (Halifax, N.S. : Saint Mary's University, 2018)

Using a sample of galaxies (M⋆ ≥ 10^10.5M_⊙) covering an effective area of ∼ 20 deg² in the CLAUDS+HSC survey, we apply a Random Forest Classifier to automatically identify merger ...
The halo shape and evolution of polar disc galaxies

Snaith, O. N.; Gibson, Brad K.; Brook, C. B.; Knebe, A.; Thacker, Robert John, 1970-; Quinn, T. R.; Governato, F.; Tissera, P. B. (Oxford University Press, 2012-09)

We examine the properties and evolution of a simulated polar disc galaxy. This galaxy is composed of two orthogonal discs, one of which contains old stars (old stellar disc) and the other both younger stars and cold gas ...
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 ...
