The astronomers reached the breakthrough as they studied a "monster galaxy" known as COSMOS-AzTEC-1, 12.4 billion light years away.
With ALMA the distant galaxy was seen with unprecedented resolution, the researchers from the National Astronomical Observatory of Japan said.
Astronomers have long wondered why monster systems can form stars at such a surprising pace.
The Atacama Large Millimeter / submillimeter Array (ALMA) observatory in Chile provided these new insights monster universe COSMOS-AzTEC-1 – on the left you see the distribution of molecular gas and on the right side you see the distribution of dust.
"This galaxy shows a star formation that got out of hand and has changed into an unstoppable star monster universe", Indicated ALMA officials in a statement." We now have the first answers ", said Professor Yun.
Astronomer Min Yun on UMass Amherst was a member of the team that discovered this galaxy in 2007, using an instrument built on UMass called AzTEC.
"We discovered that there are two different large clouds, several thousand light years away from the center," said Ken-ichi Tadaki, lead author of the study.
A team of scientists from around the world has the first accurate observation of a stargenerating "monster universe"that was formed shortly after the Big Bang." So it is surprising to find off-center clouds. "Thanks to the most extensive 16 km ALMA antenna configuration, this is the molecular gas card with the largest resolution of a distant monster universe ever made.
According to the research, the inward gravity of the galaxy is much stronger than the external pressure exerted by its molecular clouds.
To learn more about the blisteringly fast star formation in the galaxy, the global team of researchers, led by Ken-ichi Tadaki of the Japan Society for the Promotion of Science and the National Astronomical Observatory of Japan, used the Atacama Large Millimeter / submillimeter Array in Chile to map the distribution and movement of the gas.
Scientists from Japan, Mexico and the University of Massachusetts Amherst revealed previously unknown structural details about COSMOS-AzTEC-1.
"An accurate shock is that this galaxy was viewed almost thirteen billion years ago and now has a huge, ordered gas disk that is in traditional circulation as an alternative to what we expected, what would have been safe, about an unordered train that was the most theoretical destroyed reviews had predicted, "Min Yun, an astronomer at the College of Massachusetts, Amherst, and co-writer on the new work, said in an announcement. When these stars reach the end of their life cycle, the stars and the supernova explode and emit gases, which increases the external pressure.
Researchers knew that the galaxy had been properly converted into star-forming gas when they first noticed it 10 years earlier, but the necessary points of the gaseous vast revealed with ALMA were not what they expected. Because of these collapsing gas masses, stars form very quickly, but "die" in about 100 million years in this old "monster universe"That galaxy was rich in ingredients needed to form stars and the team struggled to determine the nature of the cosmic gas in the galaxy." Tadaki says: "At the moment we do not have evidence of amalgamation in this galaxy, but by observing other similar galaxies with ALMA, we want the relationship between the fusions of galaxies and monster galaxies", Said Dr. Tadaki.Picture through National Astronomical Observatory of Japan / ALMA.
