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…
Condensate cosmology -- dark energy from dark matter
Bruce A. Bassett, Martin Kunz, David Parkinson +1
Imagine a scenario in which the dark energy forms via the condensation of dark matter at some low redshift. The Compton wavelength therefore changes from small to very large at the…
Correlation-consistency cartography of the double inflation landscape
Shinji Tsujikawa, David Parkinson, Bruce A. Bassett
We show explicitly some exciting features of double-inflation: (i) it can often lead to strongly correlated adiabatic and entropy (isocurvature) power spectra. (ii) The two-field s…
Model-independent dark energy differentiation with the ISW effect
P. S. Corasaniti, B. A. Bassett, C. Ungarelli +1
We study the integrated Sachs-Wolfe (ISW) effect using a model-independent parameterization of the dark energy equation of state. Cosmic variance severely restricts the class of mo…
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,…
When can preheating affect the CMB?
Shinji Tsujikawa, Bruce A. Bassett
We discuss the principles governing the selection of inflationary models for which preheating can affect the CMB. This is a (fairly small) subset of those models which have non-neg…
A late-time transition in the cosmic dark energy?
Bruce A. Bassett, Martin Kunz, Joseph Silk +1
We study constraints from the latest CMB, large scale structure (2dF, Abell/ACO, PSCz) and SN1a data on dark energy models with a sharp transition in their equation of state, w(z).…
