Descrizione
The Cosmic Microwave Background (CMB) is our most profound window into the primordial universe. While temperature maps established the $\Lambda$CDM model, the next frontier lies in polarization and spectral distortions. These signals provide a high-precision laboratory for "extreme physics" at energy scales far beyond Earth-bound accelerators. Searching for primordial B-modes offers a direct test of the inflationary paradigm and a measurement of the energy scale of the early universe via gravitational waves. Minute deviations from the blackbody spectrum act as a fossil record of energy injection, probing dark matter decay and the damping of primordial fluctuations. Together, these observables allow us to investigate the universe's earliest moments at the highest conceivable energy. In this talk, I will review the potential of these signatures and provide an overview of current experimental efforts and upcoming missions.
