New images from the Event Horizon Telescope (EHT) collaboration have revealed a dynamic environment with changing polarization patterns caused by the magnetic fields of the supermassive black hole in the center of M87.

Multi-year Event Horizon Telescope observations capture evolving polarization patterns around the supermassive black hole and reveal radio emission from the jet base more

The “Eye of Sauron” shows the plasma jet in the blazar PKS 1424+240, seen head-on. The jet is threaded by a nearly perfect toroidal magnetic field. High-energy gamma rays and neutrinos are strongly beamed toward Earth, even though the jet appears slow-moving from our perspective.

A computer simulation of a disk of plasma around the supermassive black hole at the center of the M87 galaxy. A new analysis of the circularly polarized, or spiraling light, in EHT observations shows that magnetic fields near the black hole are strong. These magnetic fields push back on infalling matter and help launch jets of matter at velocities near the speed of light out. Image Credit: George Wong
