Lens Einstein allowed to look at the collision of galaxies

Astronomers saw a clash of two young galaxies through gravitational lenses. This was reported in a press release on the official website of the National Radio Astronomy Observatory, who participated in the study.

Scientists have observed an object PSS J2322 +1944, located at a distance of more than 12 billion light-years away. A detailed examination of the facility was made possible by the so-called gravitational lens effect. According to Einstein's theory of relativity, the presence of mass bend space. As a result, the light beam passing near a massive object (for the formation of a lens is to be an entire galaxy or cluster of Galactic), is on a curve. If such an object located between the distant galaxy and the observer on Earth, then under certain conditions it can go up (but highly distorting) lens.

According to scientists, the image produced by gravitational lenses, like the image obtained through the bottle donyshko. As a 22-year-old student, one of the authors of the study Bryuer Brendon (Brendon Brewer) has created a computer program that is using special algorithms can restore a distorted picture.

By applying this program to data collected by means of radio VLA (Very Large Array), scientists managed to establish that the PSS J2322 +1944 is a two-unifying the galaxy. This is indicated by the fact that the presence of a cluster sverhmassivnaya black hole is not in his heart, and on the outskirts.

Most recently, a similar discovery was made by astronomers from the UK. They were able to detect a collision between two galaxies, sverhmassivnye black holes at the centers are actively cooperating. The new results suggest that the collision of galaxies were already two billion years after the Big Bang.
