The most [[http://arxiv.org/abs/1303.5076|recent CMB data]] were delivered by the ESA mission [[http://sci.esa.int/planck|Planck]]: the all-sky image realized by the Planck satellite is the most precise picture of the early Universe and the results confirm that the Universe is in agreement with Lambda-CDM model.

The CMB is a very powerful observable which can be used to rule out or to validate the cosmological models and test fundamental physics. The ITP Cosmology group employed it for instance to test [[http://arxiv.org/abs/1202.1476|varying fundamental constants]], [[http://inspirehep.net/record/1215575|early dark energy]], [[http://inspirehep.net/record/1122522|coupled dark energy]], etc. | |
