An international team led by INAF has measured for the first time the polarization of light emitted by a transitional millisecond pulsar in three different bands of the electromagnetic spectrum: X-rays, optical, and radio. The study, published in ApJL, indicates that the emission is dominated by the pulsar’s particle wind and not by the matter the pulsar itself is sucking from its companion star. The paper’s first author is our researcher Maria Cristina Baglio. Other authors include our researchers: Sergio Campana, Stefano Covino, Stefano Giarratana, Sara Elisa Motta, Paolo D’Avanzo, Giulia Illiano and Marco Messa.
