The M87* ring is imaged in polarised light

1. Story
2. The collaboration published polarimetric images of the M87* ring, mapping the orientation of magnetic fields in the emitting plasma just outside the shadow. The pattern indicates fields strong and ordered enough to resist being dragged inward by the accreting gas, which is the configuration jet-launching models require. It is the closest thing yet to a direct look at the magnetic structure that the Blandford-Znajek mechanism needs in order to work.

V55 VERIFICATION BASIS: not consulted in session; no research tool was available. Volume and article number are from recall and must be checked; a companion paper on the magnetic field is deliberately not cited separately.
