Merging history of brightest cluster galaxies (BCGs) and
their black holes
with Kim-Vy Tran and Anja von der Linden.
Using the VIMOS IFU on the VLT to examine BCGs selected from Sloan (von der Linden et al. 2007) with visually determined multiple nuclei, with double-peaked emission lines (possibly due to binary black holes) and with no discernable features (the control sample) to examine the final stages of merging in these massive galaxies that are predicted to have undergone significant numbers of recent mergers.
Galaxy evolution from 0.3 < z < 1.3 using the WiggleZ Dark
Energy Survey
with Chris Blake, Warrick Couch, Karl
Glazebrook and the WiggleZ team.
Using the AAOmega multi-fibre spectrograph on the AAT to measure the baryon acoustic oscillations and calculate the ratio of the dark energy pressure and density [w(z)] at z~0.8, i.e. the expansion rate of the distant universe, using a sample of ~200,000 emission-line galaxies over 1000 square degrees. At the moment I am determining the environmental density of these galaxies.
Radial stellar populations of brightest cluster
galaxies
with Rob Proctor.
In Brough et al. (2007) I found for a sample of 6 BCGs that these galaxies seem to have more diverse origins than we have previously thought, with those galaxies in the densest environments not seeming to have undergone any merrgers since z~2. This is not consistent with current semi-analytic models. This result requires more data to confirm whether this conclusion is correct.

Finding clusters at z~0.7 using Large Red Galaxies (LRGs) with photometric redshifts , with Chris Blake and Warrick Couch.
Multi-wavelength study of the evolution of galaxies in
groups

Forbes.
One day I will add more things to this website but for now I will always love these penguins :)
