'The cosmic eye' emerged from the clash between the two galaxies

The strong collision between two spiral galaxies IC 2163 and NGC 2207 makes an eye-like structure appear in the universe.

The ALMA telescope has captured an image of an eye-like structure in the universe that appears due to a sharp collision between two spiral galaxies IC 2163 and NGC 2207 , the Independent on November 5 reported. Research on this phenomenon was published by Astele Kaufman, an astronomer at Ohio State University, Columbus, USA.

"This type of galaxy collision is not uncommon, but very few galaxies have an eye-like structure. The galaxy's eyelids appear only a few tens of millions of years, a relatively short period of time for its life cycle. So finding a galaxy's eyelid in a new phase facilitates us to study the evolution of intergalactic collisions , " Dr. Kaufman said.

Astronomers have detailed calculations of the movement of carbon monoxide (CO), materials for star formation, in the galaxy. The results showed that the air outside the eyelid moved inside with more than 100 km / s. It then quickly decelerated, moving in chaos and finally arranging in the galaxy's rotation, instead of continuing to shift to the center.

"In addition, we found that the faster the gas layer's speed decreases, the more dense the gas molecule is. This result shows that the collision between the two planets causes the gas layers to overlap, forming star clusters. how new and eyelid-like structure is, " remarked Dr. Kaufman.

These photos also prove that computer simulations of collision between two galaxies are accurate.

"The ALMA telescope shows that the velocity of the gas molecules in the eyelids coincide with the predictions we receive from computer simulations , " Dr. Kaufman said.
