| Abstract | Relevant observations to test cosmological models have increased dramatically in the last fifteen years. The Planck space mission for the observation of Cosmic Microwave Background (CMB) has brought a large increase in the accuracy of the maps of its temperature and polarization. These results have confirmed in a spectacular way the ΛCDM model and determined the parameters attached to the present content and dynamics of of our universe with sub percent accuracy. The combination with the baryon acoustic oscillations measurements made these even tighter. The predictions from the inflation paradigm of the early universe physics have been confirmed. The tensor to scalor modes ratio emerging from the early universe is only bounded by an upper limit. Extensions of the model allows to assess the validity of several key assumptions of the ΛCDM and give implications for some parameters of the standard model of particles and interactions. All this constitute now a standard model of cosmology and particle physics which explains a very large body of observations. |
