Madrid. (EP) -. Scientists have discovered a Young Galaxy acting in a mature manner unexpectedly . The galaxy, called S0901, is turning a typical leisurely way to the more developed galaxies like our Milky Way spiral.
“Usually, when astronomers analyzed galaxies at an early age, is find that turbulence plays a much more important than it does in modern galaxies role. But S0901 is a clear exception to this pattern, “said James Rhoads of Arizona State University, Tempe, lead author of the research, that will appear in the May 20 edition of the Astrophysical Journal .In the light of this galaxy has taken 10,000 million years to reach us through space , so we are seeing when I was relatively young.
The discovery was made using the Herschel Space Observatory, a mission of the European Space Agency, with important NASA contributions. “This is a really surprising result that reminds us that still do not understand many details of the evolution of the Universe. Instruments like Herschel help us understand this complex history,” said Paul Goldsmith, Herschel project scientist at the Jet Propulsion Laboratory of NASA.
When galaxies form, accumulate mass because its gravity attracts external vast clouds of gas. As the clouds of gas entering a particular galaxy fall into random orbits. These messy roads cause turbulence in the host galaxy, which may lead to the formation of stars.
To investigate the internal conditions of the galaxies in formation, Sangeeta Malhotra and Rhoads, also of Arizona State University and his colleagues focused on two young galaxies, one S0901.a cosmic magnifying glass Studio
Using a cosmic magnifying glass known as gravitational lensing The researchers got a better view of galaxies. An instrument of Herschel, the Heterodyne Instrument for the Far Infrared (HIFI), was able to collect the signature of ionized carbon, revealing the movement of molecules of gas in galaxies. This movement was much softer than expected in S0901 Galaxy.
The results for the second galaxy also hinted also a quiet rotation, but were less clear. “Galaxies 10,000 million years ago were producing stars more actively than at present,” says Malhotra. “Usually, they also show more turbulence, probably due to gas accumulating faster that modern galaxy. But here we have cases in which an early galaxy rotation combines the calm of a modern active star formation with their partners. “More observations with telescopes should help reveal whether other galaxies ways behave similarly, or if S0901 is oddly ahead of its time.
