Scientists reported that the VLA radio telescope is probably able to detect in the galaxy, Cygnus A, which is the first radio galaxy in the history of observations, the second a big Black Hole. In the Astrophysical journal write that the object was hidden from astronomers for over 20 years.
Rick Perley (Rick Perley) from the National radio astronomy Observatory, USA in Socorro recalls that in 1980, the year the VLA was already taking pictures of this galaxy, who then demonstrated the potential of radio astronomy. Then, when the telescope was upgraded in 2012, astronomers decided to make new pictures Swan and was surprised to find in the center of the galaxy a new feature that informed the photographs were absent.
Swan A is a galaxy with a big cluster of stars. To see it in optical range is impossible from a distance, but you can see the radio emission. Every second galaxy Swan And allocates as much energy as would be allocated 260 billion of our Suns. Source of energy is a powerful quasars active Black Holes in the centers of radio galaxies, which are high velocity throw of the trapped matter in the form of bundles of hot matter in intergalactic space. Such beams are referred to as advanced jets, they glow brightly at radio frequencies. The footage they are visible as long, colourful tails.
VLA, watching the Swan, And in November of 2016 years, managed to display znikam nucleus, Cygnus A not one but two pairs of these tails. One pair belonged to the first Black Hole discovered several decades ago, but the second is “new”, located 1500 light years from the first.
Study of a Swan And with the help of other telescopes, including the ability to see the galaxy in other parts of the electromagnetic spectrum, confirmed the presence of massive object. There are two versions, that it was discovered. It’s either the flash from the remains of a supernova, or the powerful Black Hole, which appeared not so long ago and began to absorb the space around them. And that is the theory viable and applicable to the detected object.
However, Rick Perley believes that we are talking about a Black Hole because such powerful and long gamma-ray bursts and radio supernovae originate from very rarely.
