Unveiling the Universal Magnetic Fields of Supermassive Black Holes: A Groundbreaking Discovery by EHT

Strong magnetic fields surround Milky Way’s black hole – Science & Tech.

Astronomers have recently made a significant discovery regarding the presence of powerful magnetic fields swirling around the black hole located at the center of our Milky Way galaxy. A new image from the Event Horizon Telescope (EHT) has revealed, for the first time in polarized light, a ring of magnetic fields surrounding Sagittarius A*, the supermassive black hole at the heart of our galaxy. These magnetic fields are said to be similar to those observed around M87* black hole at the core of the M87 Galaxy. This finding leads researchers to believe that strong magnetic fields may be common among all black holes.

The new discovery was made possible through polarized light images, which allowed astronomers to isolate the magnetic field lines of the black hole. According to Sara Issaoun, a member of Harvard’s Center for Astrophysics and co-lead of the project, these images show that strong, twisted and organized magnetic fields exist near Sagittarius A*. The immense gravitational pull of supermassive black holes makes them difficult to study directly as nothing can escape their pull. However, with EHT capturing images of both M87* and Sagittarius A*, astronomers were able to view the halo of light that forms due to inflow and outflow of matter and gas around these entities.

Angelo Ricarte, another member of Harvard’s Black Hole Initiative and co-lead on this project, emphasizes that imaging polarized light emitted by hot gas surrounding black holes is crucial in understanding their structure and strength. Mariafelicia De Laurentis, deputy scientist at EHT and professor at University Naples Federico II in Italy adds that this discovery suggests a universal characteristic among supermassive black holes across different galaxies.
