Have Acoustic Oscillations been Detected in the Current Cosmic Microwave Background Data?
M. Douspis, P. G. Ferreira
Abstract
The angular power spectrum of the Cosmic Microwave Background has been measured out to sufficiently small angular scale to encompass a few acoustic oscillations. We use a phenomenological fit to the angular power spectrum to quantify the statistical significance of these oscillations and discuss the cosmological implications of such a finding.
