The Evolving Structure of Galactic Disks
Hugo Martel, Chris Brook, Sean McGee +2
Observations suggest that the structural parameters of disk galaxies have not changed greatly since redshift 1. We examine whether these observations are consistent with a cosmolog…
Evolving Disks in Cold Dark Matter Cosmology
C. B. Brook, H. Martel, B. K. Gibson +1
Despite having entered the era of "precision cosmology," the formation of galaxies within the favored CDM cosmological paradigm remains problematic. By relating our N-body/smooth p…
High-resolution N-body Simulations of Galactic Cannibalism: The Magellanic Stream
Tim W. Connors, Daisuke Kawata, Sarah T. Maddison +1
Hierarchical clustering represents the favoured paradigm for galaxy formation throughout the Universe; due to its proximity, the Magellanic system offers one of the few opportuniti…
The Chemo-Dynamical Evolution of Elliptical Galaxies: Pre-heating and AGN heating
Daisuke Kawata, Brad K. Gibson
We study the chemodynamical evolution of elliptical galaxies and their X-ray and optical properties using high-resolution cosmological simulations. Our Tree N-body/SPH code include…
