We propose to advance the knowledge of Standard Cosmological model, both from the theoretical and from the observational point of view, by making use of the most recent cosmological data, and by planning/performing new campaigns of observations with state-of-the-art instrumentation and detectors. We aim to contribute to the study of the very early Universe through observations of Cosmic Microwave Background (CMB) polarization and spectral distortions. In addition, we will contribute to the tests for the presence of Baryonic Dark Matter in filamentary structures across the network of nonlinear structures in the universe, known as the Cosmic Web, through observations of the CMB distortion due to scattering off electrons in the hot Intra Cluster Medium (ICM) of Galaxy clusters and surrounding medium (Sunyaev Zel¿dovich effect). These objectives will be pursued through the analysis of existing data and the exploitation of experiments we are currently developing as leaders or co-leaders, like: LSPE, QUBIC, COSMO, OLIMPO, MISTRAL. In addition, we are leading observational efforts through regular submission of requests for observation time at the Sardinia Radio Telescope (SRT) and the Green Bank Telescope (GBT).
