Description
In this talk I will discuss about the global agreement between the most recent observations of the Cosmic Microwave Background temperature and polarization anisotropies. I will point out some emergent anomalies that cannot be fully understood within the standard ΛCDM model of cosmology, hinting at significant unaccounted-for systematics in the CMB data or at basic missed ingredients in the theory. Either way, I will show that these anomalies are responsible for a global “CMB tension” between independent experiments that persists also in extended background cos- mologies and analyze the implications for new physics beyond ΛCDM.
