Six articles published in the journal “Monthly Notices of the Royal Astronomical Society” report various aspects of the most accurate mapping of the polarization of the Milky Way’s microwave emissions. This provides a map of the galactic magnetic field thanks to the QUIJOTE (Q-U-I JOint TEnerife) experiment. The QUIJOTE Collaboration presented what is only the initial set of scientific papers in a survey that complements the ones obtained from other missions such as the one from the Planck Surveyor satellite. These results are useful to obtain new information on the structure of the Milky Way’s magnetic field and to understand the energetic processes that occurred soon after the birth of the universe.
