Observational constraints on thawing quintessence models
Timothy G Clemson, Andrew R Liddle
We use a dynamical systems approach to study thawing quintessence models, using a multi-parameter extension of the exponential potential which can approximate the form of typical t…
CMBPol Mission Concept Study: Probing Inflation with CMB Polarization
Daniel Baumann, Mark G. Jackson, Peter Adshead +56
We summarize the utility of precise cosmic microwave background (CMB) polarization measurements as probes of the physics of inflation. We focus on the prospects for using CMB measu…
Oscillations in the inflaton potential?
Cédric Pahud, Marc Kamionkowski, Andrew R Liddle
We consider a class of inflationary models with small oscillations imprinted on an otherwise smooth inflaton potential. These oscillations are manifest as oscillations in the power…
Triple unification of inflation, dark matter, and dark energy using a single field
Andrew R. Liddle, Cédric Pahud, L. Arturo Ureña-López
We construct an explicit scenario whereby the same material driving inflation in the early Universe can comprise dark matter in the present Universe, using a simple quadratic poten…
On the degeneracy between primordial tensor modes and cosmic strings in future CMB data from Planck
Jon Urrestilla, Pia Mukherjee, Andrew R. Liddle +3
While observations indicate that the predominant source of cosmic inhomogeneities are adiabatic perturbations, there are a variety of candidates to provide auxiliary trace effects,…
Planck and reionization history: a model selection view
Pia Mukherjee, Andrew R. Liddle
We use Bayesian model selection tools to forecast the Planck satellite's ability to distinguish between different models for the reionization history of the Universe, using the lar…
