Two different groups of researchers were found Oxygen in a very long distance galaxy, jads-GS-Z14-0. The invention makes astronomers Repeat how fast the galaxies are formed in the primitive universe.
Found last year, JADES-GS-Z14-0 is the most distant galaxy that has been observed so far: It took 13.4 billion years to reach us, which means we see when the universe is less than 300 million years old, which is compatible with 2% of the current age.
It is a new oxygen identification conducted with the help of a large millimeter/submillimeter range of Atacama, a network of telescopes installed in the Atacama Chile Desert This galaxy is more mature than the chemically expected.
The first author of the study explained that “it is like finding a young man who is a child who finds children”, now accepted for publication in the Astrophysical Journal magazine. Released in nature.
The results show This galaxy is graduated very quickly and is growing very fastIt keeps in a growing set of Proof that the establishment of galaxies in the primitive universe happened too fast .
Galaxies usually begin their lives completely Young starsThese are Formed mainly by light elements such as hydrogen and helium. When the stars develop, They form within heavy elements such as oxygenIO, it is scattered by the galaxy when the stars die.
At the age of 300 million, researchers felt that the universe filled with huge aspects of galaxies was still small. , However, however, Two studies conducted with the Spirit indicate that there are 10 times more heavy elements than the expected in the Jades-GS-GS-Zed 14-0 Galaxy.
It refers to reckless detection of oxygen in Jads-GS-Z14-0 The Galaxies may have been very fast after the Big Bang than the past thought.
“These very unexpected results surprised me because they open A new perspective on the early stages of galaxy evolution“The chief author of the article agreed for publication at the Astronomy & Astrophysics Specialty magazine said Stephano Carnia.The proof that the galaxy is already mature is still raising questions about when and how the galaxies are formed in the primitive universe”.
A. Oxygen Detection allowed astronomers to measure a distance to Jads-GS-Z14-0. “This identity of the soul gives us This is an unusual accurate measure of the distance where the galaxy is0.005 %with uncertainty. This level of accuracy, which is in accordance with the accuracy of 5 cm at a distance of 1 km, helps us to understand the characteristics of long distance galaxies, ”adds the co -author of the study, Elinora Pallanti.

Jades-GS-Z14-0 is first discovered with James Web Space Telescope, which is necessary Use the Spirit to verify and determine the great distance from this galaxy landEmphasized the ESO.
