The Spanish National Research Council (CSIC), through the Institute of Space Sciences (ICE-CSIC) and the Institute of Astrophysics of Andalusia (IAA-CSIC), participated in this international study, published in The Astrophysical Journal (ApJ). For the first time, ALMA is tracking polarized light to map the magnetic fields in the high-speed winds of Arp 220, an ultraluminous infrared galaxy.
