So, what is happening? Well, research directed by the University of Southampton has located reddish “flashes” coming from a comparatively close black hole, V404 Cygni, sp,e 7,900 light years from Earth. The flashes happened on the span of 14 days in June 2015, when the black hole went through a lot of action.
The reddish colour is because of the speed of the explosions, that has been recorded by the ULTRACAM super fast imaging camera on the William Herschel Telescope on the Canary Islands. Each flash was extremely fast, lasting only 1/40th of a second, and having a power output equal to about one thousand Suns.
Piecing together clues in regards to the color, speed, as well as the electricity of the flashes, we reason this light will be emitted in the bottom of the black hole jet.”
The fit of action in charge of the flashes that were unpredictable, the last of which happened in 1989, was due to the black hole. And in the bottom of the jets, these very brief but very glowing red flashes were created.
Although magnetic fields are considered to play a part just how the jets are generated isn’t completely understood. Maybe some answers could be provided by these flashes, however they might also help show material is consumed by black holes and subsequently ejected.
We suppose that when the black hole was being force fed by its own orbiting star, it responded violently by ejecting material as a fast-moving jet,” said Dr. Gandhi. The 2015 occasion has substantially prompted astronomers to coordinate global efforts to find future outbursts.”.
