Astronomers watch Galaxy scrutiny with a beam of radiation

In the cold, the old tributaries of the universe, two galaxies are put in a battle that was raging for billions of years. But it is not a fair battle, a team of astronomers was found recently, as one of the galaxies used Quasar to the other, which hinders its development strongly.

The “Joust Costume” team noticed, as they called the interaction, using the large Subilemeter (Alma) and the very large Southern Observatory telescope. The researchers witnessed something strange: one galaxy shoots Radiation Directly to another, which disrupts its ability to form new stars. Team results, Published Today in nature, he presented a seat in the front row to some of the most intense violence of the universe galaxies.

The interaction is so far away that the light in the pictures took 11 billion years to reach us. The cosmic fire appears as was the case when the universe was only 18 % of its current age. Although it looks clear and in the image above, the galaxies actually swing towards each other with more than 311 miles per second (500 km per second).

“We have discovered a quasar – the result of the merging of two galaxies – which is actively converting the gas structure in its accompanying galaxy,” Pascuer Netorido said in an email message. “The idea that the merging of the galaxy that leads to parallels has been proposed long ago, mainly supported by statistical studies of the host of the galaxy.” “In our case, we arrested the galaxies in the act.”

The team found that the radiation from Quasar’s One Galaxy – the essence of an active galaxy supported by a super black hole – was disrupting the areas in the other galaxy. This energy shoots directly to the other galaxy like Lance, and cut through clouds of gas and dust. Because of the turmoil, researchers say, the areas are likely to be very small so that they do not constitute new stars; The Al -Kawazar galaxy sabotated its opponent’s ability to give birth to a new light.

“We see for the first time the effect of the kawazar radiation directly on the internal structure of the gas in an ordinary galaxy otherwise,” said Sergey Balshef, author of the study’s study study and researcher at the IFFE Institute in Russia, in ESO, in ESO. Release.

But the galaxy with the Kawazar not only cuts from the other – it also turns itself. While galaxies exceed each other, the interaction represents gas towards the central black hole in Quasar, providing it with more violent equipment.

The unique interaction was made thanks to the high accuracy of pain, which allowed astronomers to see that the source of light in the deep space was actually two galaxies (the previous notes made things closely diverged as one entity). ESO X-Shooter examined the Kawazar light, helping researchers to understand how radiation affects the other galaxy.

There is more to discover beyond the horizon – and I am not talking about The horizon of the event. Tools like next Very large telescope (ELT) can allow scientists to dissect more of these ancient Hungarian quarrels, giving us a clearer picture of how to form the parallels of the galaxies in which they live – and destroy those they do not.
