Scientists have discovered a unique feature of a distant galaxy

Ученые обнаружили уникальную особенность далекой галактики

Galaxy is very different from the other galaxies.

Far away in space located a secluded galaxy. It is very poorly lit, however, have changed little over billions of years – and astronomers are not sure how this galaxy was in its place and how did its formation, according to the with reference to

Galaxy DGSAT I open in 2016, belongs to the class sverhdorogih galaxies, i.e. galaxies having relatively large dimensions at low luminosity. But this unusual galaxy violates many of the rules derived for sverhdorogih galaxies.

Most of the other sverhdorogih galaxies (a concept relatively new to astronomers) are located within densely populated, bustling clusters of galaxies. Astronomers believe that the strong collisions of these clusters in the space are thrown like confetti from firecrackers, cordifolia galaxy.

However, the galaxy DGSAT I has a secluded position. She had experienced throughout its existence of collisions with other galaxies and therefore is likely to have changed little since the time of its formation, according to a statement made by the researchers from the Observatory. Keck, located in Hawaii.

To explain the origin of the galaxy DGSAT I researchers analyzed the chemical composition using the spectroscope Cosmic Web Imager Observatory them. Cake. The data obtained showed that this galaxy is not only “pale”, but “anemic” in its composition was discovered low in relation to magnesium in iron. This fact is very unusual because usually by supernova explosions in space are thrown both of these metals in a certain ratio.

“While we do not fully understand the observed correlation between these elements, but one of the working versions suggests that powerful supernova explosions has led to the fact that the size of the galaxy was pulsing in the era of its formation, with the result that the ratio of magnesium to iron increased,” – said one of the study’s authors Aaron Romanowski from Observatories, University of California, USA.

A study published in the journal Monthly Notices of the Royal Astronomical Society.
