Since I first discovered in 1989, this black hole has been a mystery to astronomers. According to its most recent observations, it has a special feature: spits "bullets" PlasmaAfter years of research, he, the team was able to learn more about their performance and results, published this week in the journal Nature.
This black hole is 8000 light years from Earth and She & # 39 is part of a binary system known as V404 Cygni in the Milky Way. After 26 years of inactivity, the experts pointed out that 2015 has been "woken up" in a strange way.
In this new study, published they have found how it works internally"During the outbreak, to observe the details of jet emissions, if the material is ejected at very high speed black hole," said Simon Migliari, co-author of the article.
The Jets seem to be rapidly rotating, as the High plasma cloudsOnly a few minutes of each other, you are shooting in different directions. "This is one of the most unusual systems found black holes," said lead author James Miller-Jones, from the International Center of the University of the curtain for radio astronomy research (ICRAR, for its acronym in English).
V404 Cygni was first identified as a black hole in 1989, when he started a huge explosion and the radiation jets. Astronomers observe a photographic plate found file after previous outbreaks in 1938 and 1956 observations.
Associate Professor Miller-Jones V404 Cygni said that when he woke up again in 2015, for two weeks, Telescopes around the world set up to study what is going on.
If the expert and his team analyzed this mysterious black hole, they saw that their planes behave in a way never seen before. What is commonly thought that the jets are fired directly from black holes, poles, these jets are fired in different directions at different times. And they quickly changing direction.
The study was based on observations with the Very Long Baseline Array, a radio telescope of continental size, consisting of ten antennas in the United States, the Virgin Islands in the Caribbean to Hawaii.
Other study co-authors, Alex Tetarenko, a recent graduate of the University of Alberta PhD and currently with the & # 39; is a member of the East Asia Observatory, who works in Hawaii, according to the speed at which the jet had to change direction scientists had to use a very different approach for the majority of radio observations.
"As a rule, radio telescopes they produce one image after a few hours of observation. But these planes were changing so fast that the images of four hours saw only a blur. It was like trying to take a picture of a waterfall with a shutter speed of a second, "said Tetarenko.
It was, as a team 103 individual images obtained, Each of about 70 seconds duration, and They joined the film"The only way we could see the changes in a very short period of time," said the expert.
