BaR-SPOrt: AN EXPERIMENT TO MEASURE THE LINEARLY POLARIZED SKY EMISSION FROM BOTH THE COSMIC MICROWAVE BACKGROUND AND FOREGROUNDS

摘要

The BaR-SPOrt experiment is aimed at measuring the polarization of the microwave sky at 32 and 90 GHz with sub-degree angular resolution. In this spectral and angular window it is possible to detect the polarization of the cosmic microwave background, which is one of the most ambitious goals of the today astrophysics. The experiment has been designed to fly onboard a Long Duration Balloon to be launched from polar regions, where it is possible to observe low foreground emission sky patches situated at high galactic latitudes.
