Description
The cosmic microwave background (CMB) is a powerful source of information about all epochs of the Universe, playing a key role in shaping the standard model of cosmology. Data from the ESA Planck mission allowed us to deliver the most precise measurement of the CMB temperature anisotropy pattern, along with leading-edge observations of polarization. In this talk, I will discuss future directions in CMB science, particularly in constraining cosmic inflation and probing the Universe's dark sector. I will highlight the power of polarization data and the synergies between CMB observations and upcoming deep and wide galaxy surveys. As these surveys collect vast amounts of data — complementary to the CMB on a wider range of physical scales and at different cosmic epochs — a promising avenue is cross-correlating these different probes which are sensitive to the same underlying physics. This approach maximizes scientific returns while mitigating the impact of instrumental and astrophysical systematics that might affect individual datasets. This work is especially timely as we prepare for the scientific exploitation of the ESA Euclid mission.
