Galactic Chemical Evolution
Brad K. Gibson, Yeshe Fenner, Agostino Renda +2
The primary present-day observables upon which theories of galaxy evolution are based are a system's morphology, dynamics, colour, and chemistry. Individually, each provides an imp…
Stellar Halo Constraints on Simulated Late Type Galaxies
Chris B. Brook, Daisuke Kawata, Brad K. Gibson +1
How do late type spiral galaxies form within the context of a CDM cosmology? We contrast N-body, smoothed particle hydrodynamical simulations of galaxy formation which employ two d…
Satellite galaxies in cosmological dark matter halos
Stuart P. D. Gill, Alexander Knebe, Brad K. Gibson
We present preliminary results from a series of high-resolution N-body simulations that focus on 8 dark matter halos each of order a million particles within the virial radius. We…
Anisotropy in the Distribution of Satellite Galaxy Orbits
Alexander Knebe, Stuart P. D. Gill, Brad K. Gibson +3
Nearby clusters such as Virgo and Coma possess galaxy distributions which tend to be aligned with the principal axis of the cluster itself. This has also been confirmed by a recent…
The Galaxy's Eating Habits
M. E. Putman, C. Thom, B. K. Gibson +1
The possibility of a gaseous halo stream which was stripped from the Sagittarius dwarf galaxy is presented. The total mass of the neutral hydrogen along the orbit of the Sgr dwarf…
An HI census of Loose Groups of Galaxies
D. J. Pisano, David G. Barnes, Brad K. Gibson +3
We present results from our Parkes Multibeam HI survey of 3 loose groups of galaxies that are analogous to the Local Group. This is a survey of groups containing only spiral galaxi…
