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…
The Effective Theory of Quintessence: the w<-1 Side Unveiled
Paolo Creminelli, Guido D'Amico, Jorge Noreña +1
We study generic single-field dark energy models, by a parametrization of the most general theory of their perturbations around a given background, including higher derivative term…
Action approach to cosmological perturbations: the 2nd order metric in matter dominance
Lotfi Boubekeur, Paolo Creminelli, Jorge Norena +1
We study nonlinear cosmological perturbations during the post-inflationary evolution, using the equivalence between a perfect barotropic fluid and a derivatively coupled scalar fie…
Limits on f_NL parameters from WMAP 3yr data
Paolo Creminelli, Leonardo Senatore, Matias Zaldarriaga +1
We analyze the 3-year WMAP data and look for a deviation from Gaussianity in the form of a 3-point function that has either of the two theoretically motivated shapes: local and equ…
Limits on non-Gaussianities from WMAP data
Paolo Creminelli, Alberto Nicolis, Leonardo Senatore +2
We develop a method to constrain the level of non-Gaussianity of density perturbations when the 3-point function is of the "equilateral" type. Departures from Gaussianity of this f…
Single field consistency relation for the 3-point function
Paolo Creminelli, Matias Zaldarriaga
We point out the existence of a consistency relation involving the 3-point function of scalar perturbations which is valid in any inflationary model, independently of the inflaton…
