a Strange form of radio galaxies for a long time did not give astronomers rest.
the Mystery of the strange X-shape radio galaxies PKS 2014-55 finally solved, claims a team of American and South African researchers in an article published in the arXiv.
They published very detailed pictures of this largest of the ever detected radio galaxies in the form of the letter H. Image obtained by using the MeerKAT radio telescope in South Africa.
the photo PKS 2014-55 like a bright butterfly. It is a beautiful glow can only look at the radio telescope.
PKS 2014-55 is in the cluster of galaxies Abell 3667, discovered more than 60 years ago. A strange form of radio galaxies for a long time did not give astronomers rest. The fact that PKS 2014-55 two pairs of giant radiolopolis, whereas X-shape radio galaxies have only one. The blades consist of hot streams of electrons emanating from a supermassive black hole at our galaxy’s heart.
Trying to explain this phenomenon, scientists have voiced several hypotheses. According to one of them, PKS 2014-55 two pairs of radiolopolis, because at its center are two black holes. According to the second, the black hole at the center of a sudden change the axis of rotation, so there was a second pair of blades.
Surveillance MeerKAT has opened a third possibility: actually one pair of blades is outgoing flows, and the second turning back.
