Multiple Peaks in the CMB

Abstract

Recent measurements of the Cosmic Microwave Background Anisotropy have provided evidence for the presence of oscillations in the angular power spectrum. These oscillations are a wonderful confirmation of the standard cosmological scenario and allow us to derive constraints on many cosmological, astrophysical and inflationary parameters. If the discovery is confirmed by future experiments, opportunities may appear, for example, to constrain dark energy, variations in fundamental constants and neutrino physics.
