CMB polarization. We investigate the prospects of achieving this goal in the presence of large-scale, di use galactic foreground emission by using non-Gaussian sky simulations and exploit multi-frequency information to clean those.

We show that, while prior to foreground cleaning,Author: Dominic Beck, Josquin Errard, Radek Stompor.

Polarization leakage of foreground synchrotron emission is a critical issue in H i intensity mapping experiments. While the sought-after H i emission is unpolarized, polarized foregrounds such as Galactic and extragalactic synchrotron radiation, if coupled with.

We use a map-based method for reducing the Galactic foreground and study how the residual foreground limits a measurement of the primordial B-mode polarization.

The foreground reduction technique we use is motivated by the "template cleaning method" used by the Wilkinson Microwave Anisotropy Probe (WMAP) team (Page et al. ; Gold et al Cited by: We discuss the technique and results of a measurement of the linear polarization of the Cosmic Background Radiation.

Data taken between May and February from both the northern hemisphere (Berkeley Lat. 38{sup o}N) and the southern hemisphere (Lima Lat.

12{sup o}s) over 11 declinations from {sup o} to +63{sup o} show the radiation to be essentially unpolarized. In this paper we discuss the latest developments of the STRIP instrument of the "Large Scale Polarization Explorer" (LSPE) experiment.

LSPE is a novel project that combines ground-based (STRIP) and balloon-borne (SWIPE) polarization measurements of the microwave sky on large angular scales to attempt a detection of the "B-modes" of the Cosmic Microwave Background Author: Cristian Franceschet, Sabrina Realini, Aniello Mennella, Giuseppe Addamo, Alessandro Baù, Paola M.

The cosmic microwave background radiation is an emission of uniform, black body thermal energy coming from all parts of the sky. The radiation is isotropic to roughly one part inthe root mean square variations are only 18 µK, after subtracting out a dipole anisotropy from the Doppler shift of the background radiation.

The latter is caused by the peculiar velocity of the Sun .
