On the non-Gaussianity from Recombination
Nicola Bartolo, Antonio Riotto
The non-linear effects operating at the recombination epoch generate a non-Gaussian signal in the CMB anisotropies. Such a contribution is relevant because it represents a major pa…
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…
Impact of Uncertainties in the Cosmological Parameters on the Measurement of Primordial non-Gaussianity
M. Liguori, A. Riotto
We study the impact of cosmological parameters' uncertainties on estimates of the primordial NG parameter f_NL in local and equilateral models of non-Gaussianity. We show that prop…
Parameterizing the Effect of Dark Energy Perturbations on the Growth of Structures
G. Ballesteros, A. Riotto
We present an analytical fit to the growth function of the dark matter perturbations when dark energy perturbations are present. The growth index depends upon the dark energy equat…
On cosmological observables in a swiss-cheese universe (Conference proceeding)
Valerio Marra
By means of a toy Swiss-cheese cosmological model we will discuss how to set up and carry out in a physically meaningful way the idea of back-reaction, according to which dark ener…
The impact of cosmic neutrinos on the gravitational-wave background
A. Mangilli, N. Bartolo, S. Matarrese +1
We obtain the equation governing the evolution of the cosmological gravitational-wave background, accounting for the presence of cosmic neutrinos, up to second order in perturbatio…
