Scientists from Missouri University have discovered 300 unusually bright objects in space that can be from the earliest galaxies. The study is based on infrared images obtained through the powerful "James Web" space telescope. The work was published in The Astrophysical Journal (Astrojournal).
"If at least some of these facilities are really early galaxies, it can change our ideas at the beginning of the universe on the formation of galaxies at the beginning of the universe," said Professor of Astronomy.
The so-called DropOut technique has been used to search, in which case distant galaxies are separated according to the fact that they are visible in red length channels, but "disappears" in more blue areas. This is connected with the effect of the Liamis flight. Ultraviolet light of such objects is absorbed by intergalactic hydrogen, and due to red deviation, this feature is transferred to the spectrum infrared sector.
In order to adjust the settings, scientists have used a method of energy spectral distribution, which allows you to estimate the approximate red deviations, age and mass, even without spectroscopy. However, the final confirmation is possible only through spectroscopic observations, which will give a clear "signature" of each galaxy.
One of the objects has already been approved as the galaxy of the early universe, but the authors emphasize, additional data is needed.
"At least a few such confirmations will be enough to reconsider the existing theories of galaxies," said Yang.
