New!! Observations of our Event Horizon Telescope () collaboration have uncovered strong & organized magnetic fields spiraling around the edge of the supermassive black hole Sagittarius A* (Sgr A*). Images in polarized light of the in the Milky Way center reveal structures similar to those in M87*, suggesting that strong magnetic fields may be common to all black holes. This also hints toward a hidden jet in Sgr A*!

Image of the supermassive black hole in the Galactic Center. An orange ring with three bright regions and hair-like structures. The orange color shows total intensity of the mm-wave radio emission, the fine lines indicate polarization direction. Magnetic fields are typically at right angle to those lines. Credit: Event Horizon Telescope 2024 Blue oval with a red center line and wavy hairlike structures showing the polarized radio lighter measured by the Planck satellite of the entire sky with the Milky Way prominently along the horizontal center line. Inset toward the center show an inclined ring and two spikes, which are gas streamers in the Galactic Center measured by Sofia (DLR/NASA). Inset to the left shows the polarized ring of the black hole radio image from the EHT again. Two orange rings with hairy spiral structures.

BTW, 30 years ago, I proposed a model for the black hole in the center of the Milky Way saying that the radio mission can be explained by a hidden jet. This predicted the existence of radio light at the edge of the black hole and led to the prediction of a black hole shadow, that was observed two years ago by the EHT. The idea of a hidden jet remained controversial. It is exciting to see the tantalizing evidence coming from the polarization images, which supports the hypothesis.

@hfalcke Spectacular.

@hfalcke I would like to know more about why you believed black holes existed in the universe before they were observed, as well as the actual properties of the rings of different types of black holes.

@hfalcke While reading your new book, I am curious about the process you used to think.
