Cosmological constraints from the correlation function of galaxy clusters
James Robinson
I compare various semi-analytic models for the bias of dark matter halos with halo clustering properties observed in recent numerical simulations. The best fitting model is one bas…
Constraining Primordial Non-Gaussianity With the Abundance of High Redshift Clusters
James Robinson, Eric Gawiser, Joseph Silk
We show how observations of the evolution of the galaxy cluster number abundance can be used to constrain primordial non-Gaussianity in the universe. We carry out a maximum likelih…
Evolution of the cluster abundance in non-Gaussian models
James Robinson, Jonathan E. Baker
We carry out N-body simulations of several non-Gaussian structure formation models, including Peebles' isocurvature cold dark matter model, cosmic string models, and a model with p…
WOMBAT & FORECAST: Making Realistic Maps of the Microwave Sky
Andrew H. Jaffe, Eric Gawiser, Douglas Finkbeiner +11
The Wavelength-Oriented Microwave Background Analysis Team (WOMBAT) is constructing microwave maps which will be more realistic than previous simulations. Our foreground models rep…
The WOMBAT Challenge: A "Hounds and Hares" Exercise for Cosmology
Eric Gawiser, Douglas Finkbeiner, Andrew Jaffe +10
The Wavelength-Oriented Microwave Background Analysis Team (WOMBAT) is constructing microwave skymaps which will be more realistic than previous simulations. Our foreground models…
A Simultaneous Constraint on the Amplitude and Gaussianity of Mass Fluctuations in the Universe
James Robinson, Eric Gawiser, Joseph Silk
We consider constraints on the amplitude of mass fluctuations in the universe, sigma_8, derived from two simple observations: the present number density of clusters and the amplitu…
