Inflation and Precision Cosmology
Jerome Martin
A brief review of inflation is presented. After having demonstrated the generality of the inflationary mechanism, the emphasize is put on its simplest realization, namely the singl…
On the "Causality Argument" in Bouncing Cosmologies
Jerome Martin, Patrick Peter
We exhibit a situation in which cosmological perturbations of astrophysical relevance propagating through a bounce are affected in a scale-dependent way. Involving only the evoluti…
Superimposed Oscillations in the WMAP Data?
Jerome Martin, Christophe Ringeval
The possibility that the cosmic variance outliers present in the recently released WMAP multipole moments are due to oscillations in the primordial power spectrum is investigated.…
Parametric amplification of metric fluctuations through a bouncing phase
Jerome Martin, Patrick Peter
We clarify the properties of the behavior of classical cosmological perturbations when the Universe experiences a bounce. This is done in the simplest possible case for which gravi…
On the Dependence of the Spectra of Fluctuations in Inflationary Cosmology on Trans-Planckian Physics
Jerome Martin, R. H. Brandenberger
We calculate the power spectrum of metric fluctuations in inflationary cosmology starting with initial conditions which are imposed mode by mode when the wavelength equals some cri…
