Following on from Duffy et al. (2010), in this paper we considered the same simulated haloes when "Modelling neutral hydrogen in galaxies using cosmological hydrodynamical simulations". This studied the baryonic properties of simulated haloes; focussing on Neutral Hydrogen, but also Molecular Hydrogen and Stellar masses as a function of cosmic time, halo mass and baryonic physics. With this paper I made the Victorian State Finals for the Fresh Science Award. Reference: Duffy, Kay, Battye, Booth, Dalla Vecchia, Schaye 2012 MNRAS 420 2799

My first SPH simulation paper on the "Impact of baryon physics on dark matter structures: a detailed simulation study of halo density profiles". It demonstrated that the physics of galaxy formation can (surprisingly) strongly affect the dark matter distribution. It won the "Best Paper by a UWA Early Career Researcher" award.

This was the main simulation paper for the OverWhelmingly Large Simulations (OWLS) effort that I was involved with during my PhD. This paper in particular focuses on the impact that different baryonic processes can have on the global star-formation rate, amongst many other effects.

My first N-body simulation paper (as well as Letter) on the topic of "Dark matter halo concentrations in the Wilkinson Microwave Anisotropy Probe year 5 cosmology" when I was based at Leiden Observatory. It demonstrated a fascinating inverse relation between the concentration (compactness) of a dark matter object and the mass of said object.

My first publication in a journal, on the subject of "Galaxy redshift surveys selected by neutral hydrogen using the Five-hundred metre Aperture Spherical Telescope". The telescope will be a fantastic survey instrument, capable of detecting millions to hundreds of millions of galaxies around us for billions of light years.
