UNC Physics Colloquium-Prof. Eleonora Di Valentino

The scenario that has been selected as the standard cosmological model
is the Lambda Cold Dark Matter (ΛCDM), which provides a remarkable fit
to the bulk of available cosmological data. However, discrepancies among
key cosmological parameters of the model have emerged with different
statistical significance. While some portion of these discrepancies may
be due to systematic errors, their persistence across probes can
indicate a failure of the canonical ΛCDM model. I will review these
tensions, showing some interesting extended cosmological scenarios that
can alleviate them.
