Inflation with moderately sharp features in the speed of sound: GSR and in-in formalism for power spectrum and bispectrum
Ana Achucarro, Vicente Atal, Bin Hu +2
We continue the study of mild transient reductions in the speed of sound of the adiabatic mode during inflation, of their effect on the primordial power spectrum and bispectrum, an…

Localized correlated features in the CMB power spectrum and primordial bispectrum from a transient reduction in the speed of sound
Ana Achucarro, Vicente Atal, Pablo Ortiz +1
The first year of observations by the Planck satellite mission shows that the cosmic microwave background (CMB) fluctuations are consistent with gaussian statistics in the primordi…
