QUBIC
QUBIC (Q and U Bolometric Interferometer for Cosmology) is an experiment aimed at measuring the polarization of the cosmic microwave background (CMB), with high precision and exceptional control of systematic effects and local foregrounds. This measurement, and in particular the measurement of the curl component (B-modes) represents a challenge and an opportunity to study unexplored regions of cosmology (the very early universe) and fundamental physics (the physics of inflation at ultra high energies).
While a number of ground based, stratospheric balloon, and satellite CMB polarization missions use imaging Stokes polarimeters, QUBIC uses an orthogonal method, working as a Fizeau interferometer, optimizing the control of systematics while maintaining the sensitivity advantage of bolometer arrays. QUBIC is an international collaboration involving scientists in France, Italy, UK, Argentina, USA.
Roma1 contributes to this experiment being in charge of the main cryogenic system, the cryogenic mechanism for the polarization modulator, and contributing to the optical system, the calibrations, the data analysis and the scientific exploitation of the results. Fundings in Italy initially by PNRA, since 2017 by INFN.
