Dark energy effects in the Cosmic Microwave Background Radiation

Abstract

Understanding the nature of the dark energy is one of the most important task in cosmology. In principle several cosmological observations can be used to discriminate amid a static cosmological constant contribution and a dynamical quintessence component. In view of the upcoming high resolution CMB experiments, using a model independent approach we study the dark energy imprint in the CMB anisotropy power spectrum and the degeneracy with other cosmological parameters.
