Astronomers have a rough understanding of how galaxies emit jets from their cores. Galaxy cores also blow out winds of ionized gas, for which researchers lack a general explanation. SRON astronomers have now found a correlation between jets and winds, suggesting magnetic fields as a common cause. The study is published in Astronomy & Astrophysics.
