Black holes are known for their power: gravity is so strong that it is capable of absorbing stars and releasing matter in space with almost the speed of light. But the reality does not match our assumptions.
Researchers at the University of Florida found that the magnetic fields of breaks in the fabric of the universe are much weaker than previously thought.
The first accurate measurements of the magnetic field were made in the V404 Cygnus black hole. It is 8000 light-years distant from us and stretches 40 miles wide. It turned out that magnetic energy around a black hole is 400 times weaker than previous estimates showed.
New data lead to an understanding of how black hole magnetism functions, and also opens up a different perspective on the behavior of matter under the most extreme conditions. Measurements will also make it possible to understand how jets of particles moving at almost light speed fly out of magnetic fields, while everything else is sucked into the abyss. Information received in 2015 during a rare flash of a black hole. The 34-foot Large Canary Telescope (the largest in the world), on which the CIRCLE IR camera was installed, was used for observation.
Particular attention is attracted to smaller jets in black holes. Such flashes occur suddenly, and they are short-lived. For example, the outbreak of V404 Cygnus lasted only a couple of weeks. Prior to this, a similar event was recorded in 1989.
