Polarimetry of Anomalous Microwave Emission: Implication for B-mode Polarization Detection and Galactic Science

ended

Anomalous Microwave Emission (AME) is potentially polarized in the frequency range [1-100] GHz. The polarization properties of this astrophysical signal have to be characterized and understood completely for one willing to remove Galactic foregrounds in order to detect B-mode polarization for cosmology. The characterization of AME polarization properties is also fundamental in term of Galactic Astrophysics to understand the mechanisms producing the AME. The PolAME project aims to use the QUIJOTE-CMB experiment and its two instruments (the MFI and the TGI) for measuring the degree of polarization of the AME in the domain range [10-30] GHz on a sample of selected sources. This new data, in addition to new C-BASS data and the WMAP and PLANCK maps and ancillary data will be compared to theory and state-of-the-art modelling results. The Galactic science community will greatly benefit the new advances that will be provided by the PolAME project. The main outcome of this project will lead to a stronger characterization of the Galactic Polarized Foregrounds which is fundamental for cosmology. Knew knowledge will be produced about our understanding of the nature of the AME and dust grain evolution processes in our Galaxy.
