Cosmology

Cosmology is the study of the large scale structure of the Universe, as well as its dynamics. Our group has been involved in the study and development of cosmological models, in particular to explain the accelerated phases of the cosmological evolution, dubbed inflationary phases.

For our latest developments/activities in this area, please see the listing below.

Correlations play a fundamental role in many branches of physics, from quantum mechanics to particle physics and cosmology. In particular, the astonishing homogeneity of the angular distribution of the Cosmic Microwave Background radiation across the sky (measured with high precision by the WMAP and Planck missions) requires of an inflationary epoch right after the Big Bang.
