According to them, the EHT managed to get close to the event horizon of “our” black hole and achieve a record resolution, 10 times greater than the accuracy of previous observations.
For the first time, astronomers have detected magnetic fields near the point of no return of our central black hole, popularly known as Sagittarius A*.
To study Sagittarius A* in detail, astronomers used the Event Horizon Telescope (EHT), a network of radio telescopes around the world. "These magnetic fields were predicted, but no one had ever seen them before. Our data puts decades of theoretical work on a solid practical basis." "Until now, no one had observed magnetic fields near a black hole's event horizon," said Michael Johnson of the Harvard-Smithsonian Center for Astrophysics, the author of the new study.
The dark hole at the center of our galaxy is surrounded by a hot accretion disk of matter. Scientists are currently analyzing the acquired data, which will help unravel the secrets of the unexplained radiation emanating from dark holes.
The enormous dark hole at the center of our Milky Way galaxy is receiving increasing attention. Such high resolution is required to observe the event horizons of dark holes, which have small angular sizes on the sky.
Scientists have measured the degree of light polarization in our galaxy and reached some interesting conclusions. Previously, magnetic fields were suspected around dark holes, but it was impossible to measure them because, despite their astonishing massiveness, black holes themselves are small. As a result, the light directly reveals the structure of the magnetic field.
