Scientific paper

We propose the activities for the 3rd semester of the PGMS, aimed at surveying the polarized Galactic diffuse emission along the Galactic meridian l=255 deg at 2.3 GHz. The 5 x 90 deg^2 strip crosses the low emission area of the BOOMERanG experiment selected as one of the targets for Cosmic Microwave Background Polarization (CMBP) experiments. Carried on at a frequency where the Faraday rotation effects are weak, the aim of these observations is two-fold: cosmology and Galactic physics. As for the former, it allows the study of the contamination of CMBP by synchrotron emission as a function of the Galactic latitude, in particular helping determine the effectiveness of the CMBP to investigate the primordial gravitational wave background left by Inflation. As for the second aim, it allows the investigation of the intrinsic Galactic polarized emission structure, still hidden at lower frequency, and the study of the Galactic magnetic field in the halo.
