(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] ...
-
(American Astronomical Society, 2000-04)The possibility that the Galactic spheroid was assembled from isolated, chemically distinct proto-Galactic fragments is investigated using a Monte Carlo technique designed to simulate the chemical evolution of the Galaxy ...
-
(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 ...
-
(American Astronomical Society, 2013-07-10)In the early universe, substantial relative “stream” velocities between the gas and dark matter arise due to radiation pressure and persist after recombination. To assess the impact of these velocities on high-redshift ...
-
(Halifax, N.S. : Saint Mary's University, 2023-08-03)In our current theoretical framework of galaxy formation and evolution, galaxies assemble stellar halo components through galaxy-galaxy interactions and accretion of ex-situ material. Studying this buildup of stellar haloes ...
-
(Wiley-Blackwell, 2012-09)We explore the circumgalactic medium (CGM) of two simulated star-forming galaxies with luminosities L ≈ 0.1 and 1 L★ generated using the smooth particle hydrodynamic code GASOLINE. These simulations are ...
-
(Oxford University Press, 2016-04-21)We have simulated the formation of a galaxy cluster in a [lambda] cold dark matter universe using 13 different codes modelling only gravity and non-radiative hydrodynamics (RAMSES, ART, AREPO, HYDRA and nine incarnations ...
-
(Oxford University Press, 2016-06-01)Building on the initial results of the nIFTy simulated galaxy cluster comparison, we compare and contrast the impact of baryonic physics with a single massive galaxy cluster, run with 11 state-of-the-art codes, spanning ...
-
(Wiley-Blackwell, 2011-11)We describe a new algorithm for finding substructures within dark matter haloes from N-body simulations. The algorithm relies upon the fact that dynamically distinct substructures in a halo will have a local velocity ...
