Probing the origins of voids with the CMB
L. M. Ord, M. Kunz, H. Mathis +1
In this talk presented at the 5th Rencontres du Vietnam 2004, we discuss our preliminary investigations into voids of primordial origin. We show that if voids in the cold dark matt…
Dark Energy in Chains
David Parkinson, Bruce A. Bassett, Edmund J. Copeland +2
Dark energy affects the CMB through its perturbations and affects both CMB and Sn-Ia through its background evolution. Using recent CMB and Sn-Ia data sets, together with the most…
A Tale of Two Distances
Martin Kunz, Bruce A. Bassett
There are two basic ways to measure physical distances in cosmology: One based on standard candles and one based on standard rulers. Comparing current data for each method allows u…
Did the dark energy always have a large Compton wavelength?
Bruce A. Bassett, Martin Kunz, David Parkinson +1
Until now all well-studied dark energy models proposed have very large Compton wavelengths, at all time and hence show no clustering on small scales. Evidence again…
A late-time transition in the equation of state versus Lambda-CDM
B. A. Bassett, M. Kunz, J. Silk +1
We study a model of the dark energy which exhibits a rapid change in its equation of state w(z), such as occurs in vacuum metamorphosis. We compare the model predictions with CMB,…
