"Dark matter halo concentrations in the Wilkinson Microwave Anisotropy Probe year 5 cosmology" Duffy et al. (2008b)
Alan Duffy
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.
