Bouncing Cosmological Isotropic Solutions in Scalar-Tensor Gravity
D. Polarski, A. A. Starobinsky, Y. Verbin
Bouncing non-singular isotropic cosmological solutions are investigated in a simple model of scalar-tensor gravity. New families of such solutions are found and their properties ar…
Searching for hidden mirror symmetries in CMB fluctuations from WMAP 7 year maps
F. Finelli, A. Gruppuso, F. Paci +1
We search for hidden mirror symmetries at large angular scales in the WMAP 7 year Internal Linear Combination map of CMB temperature anisotropies using global pixel based estimator…
CDM models with a BSI steplike primordial spectrum and a cosmological constant
J. Lesgourgues, D. Polarski, A. A. Starobinsky
A class of spatially-flat models with cold dark matter (CDM), a cosmological constant and a broken-scale-invariant (BSI) steplike primordial (initial) spectrum of adiabatic perturb…
Isocurvature Perturbations in Multiple Inflationary Models
D. Polarski, A. A. Starobinsky
Dynamics of long-wave isocurvature perturbations during an inflationary stage in multiple (multi-component) inflationary models is calculated analytically for the case where scalar…
Confrontation of Double-Inflationary Models with Observations
P. Peter, D. Polarski, A. A. Starobinsky
We consider double-inflationary models with two noninteracting scalar fields, a light scalar field with potential and a heavy scalar field with…
