By means of high-resolution cosmological hydrodynamical simulations of Milky Way (MW) like disc galaxies, we conduct an analysis of the associated stellar metallicity distribution functions (MDFs). After undertaking a kinematic decomposition of each... Read More about The stellar metallicity distribution of disc galaxies and bulges in cosmological simulations.

Properties of simulated Milky Way-mass galaxies in loose group and field environments (2012)
Journal Article
Few, C. G., Gibson, B. K., Courty, S., Michel-Dansac, L., Brook, C. B., & Stinson, G. S. (2012). Properties of simulated Milky Way-mass galaxies in loose group and field environments. Astronomy and Astrophysics, 547, Article ARTN A63. https://doi.org/10.1051/0004-6361/201219649

Aims. We test the validity of comparing simulated field disk galaxies with the empirical properties of systems situated within environments more comparable to loose groups, including the Milky Way's Local Group. Methods. Cosmological simulations of M... Read More about Properties of simulated Milky Way-mass galaxies in loose group and field environments.

Calibrating an updated smoothed particle hydrodynamics scheme within GCD+ (2012)
Journal Article
Kawata, D., Okamoto, T., Gibson, B. K., Barnes, D. J., & Cen, R. (2013). Calibrating an updated smoothed particle hydrodynamics scheme within GCD+. Monthly notices of the Royal Astronomical Society, 428(3), 1968-1979. https://doi.org/10.1093/mnras/sts161

We adapt a modern scheme of smoothed particle hydrodynamics (SPH) to our treeN-body/SPH galactic chemodynamics code GCD+. The applied scheme includes implementations of the artificial viscosity switch and artificial thermal conductivity proposed by M...

Hierarchical formation of bulgeless galaxies - II. Redistribution of angular momentum via galactic fountains: Bulgeless discs II (2011)
Journal Article
Brook, C. B., Stinson, G., Gibson, B. K., Roškar, R., Wadsley, J., & Quinn, T. (2012). Hierarchical formation of bulgeless galaxies - II. Redistribution of angular momentum via galactic fountains: Bulgeless discs II. Monthly notices of the Royal Astronomical Society, 419(1), 771-779. https://doi.org/10.1111/j.1365-2966.2011.19740.x

Within a fully cosmological hydrodynamical simulation, we form a galaxy which rotates at 140 kms-1, and it is characterized by two loose spiral arms and a bar, indicative of a Hubble-type SBc/d galaxy. We show that our simulated galaxy has no classic... Read More about Hierarchical formation of bulgeless galaxies - II. Redistribution of angular momentum via galactic fountains: Bulgeless discs II.

The origin of the light distribution in spiral galaxies (2009)
Journal Article

We analyse a high-resolution, fully cosmological, hydrodynamical disc galaxy simulation, to study the source of the double-exponential light profiles seen in many stellar discs, and the effects of stellar radial migration upon the spatiotemporal evol...

An HI survey of six local group analogs. I. Survey description and the search for high-velocity clouds (2007)
Journal Article

We have conducted an H I 21 cm emission-line survey using the Parkes 20 cm multibeam instrument and the Australia Telescope Compact Array (ATCA) of six loose groups of galaxies chosen to be analogs to the Local Group. The goal of this survey is to ma... Read More about An HI survey of six local group analogs. I. Survey description and the search for high-velocity clouds.

The initial-final mass relationship: Spectroscopy of white dwarfs in NGC 2099 (M37) (2004)
Journal Article

We present new observations of very faint white dwarfs (WDs) in the rich open star cluster NGC 2099 (M37). Following deep, wide-field imaging of the cluster using the Canada-France-Hawaii Telescope, we have now obtained spectroscopic observations of...
