Cosmic microwave background constraints on dark energy dynamics: analysis beyond the power spectrum
Fabio Giovi, Carlo Baccigalupi, Francesca Perrotta
We consider the distribution of the non-Gaussian signal induced by weak lensing on the primary total intensity cosmic microwave background (CMB) anisotropies. Our study focuses on…
Dark energy and CMB bispectrum
F. Giovi, C. Baccigalupi
We consider the CMB bispectrum signal induced by structure formation through the correlation between the Integrated Sachs-Wolfe and the weak lensing effect. We investigate how the…
Constraining the dark energy dynamics with the cosmic microwave background bispectrum
F. Giovi, C. Baccigalupi, F. Perrotta
We consider the influence of the dark energy dynamics at the onset of cosmic acceleration on the Cosmic Microwave Background (CMB) bispectrum, through the weak lensing effect induc…
Weak lensing, structure formation and dark energy
Fabio Giovi, Carlo Baccigalupi, Francesca Perrotta
We study how CMB bispectrum, produced by weak gravitational lensing and structure formation, can constrain the redshift evolution of the dark energy equation of state independently…
The Dyer-Roeder distance in quintessence cosmology and the estimation of H_0 through time-delays
Fabio Giovi, Franco Occhionero, Luca Amendola
We calculate analytically and numerically the Dyer-Roeder distance in perfect fluid quintessence models and give an accurate fit to the numerical solutions for all the values of th…
