First Polarized Image Around a Black Hole
On March 24th 2021, the EHT Collaboration produced the first polarized image around the black hole of M87. An azimuthal electric vector polarization pattern was found around the ring, consistent with dynamically strong magnetic fields in the accretion flow supplied to the jetted accreting supermassive black hole M87*. The Collaboration Papers VII and VIII can be found here:
