Abstract: |
The CMB polarization promises to unveil the dawn of time,
measuring the gravitational wave background emitted
by the Inflation. The CMB signal is faint, however,
and easily contaminated by the Galactic foreground emission,
accurate measurements of which are thus crucial to make CMB
observations successful. We review CMB
polarization properties and the current knowledge on the
Galactic synchrotron emission, which dominates the foregrounds
budget at low frequency. We then focus on the S-Band Polarization
All Sky Survey (S-PASS), a recently completed survey of the entire
southern sky designed to investigate the Galactic CMB foreground. |
