Constraining the shape of the CMB: A peak-by-peak analysis

Abstract: The recent measurements of the power spectrum of Cosmic Microwave Background anisotropies are in agreement with the simplest inflationary scenario and big bang nucleosynthesis constraints. However, these results rely on the assumption of a class of models based on primordial adiabatic perturbations, cold dark matter and a cosmological constant. In this paper we investigate the need for deviations from the Λ-CDM scenario by first characterizing the peaks in the spectrum using different phenomenological function… Show more
