Astronomers see a group that surprisingly appears to have no dark matter

Dark and invisible things something interlocking galaxies like a cosmic duct tape. But a team of researchers said that they had discovered a distant galaxy without black matter, which they discovered that could impair the understanding of black matter and the formation of galaxies.

Although we cannot see black objects (scientists believe they do about 27% of the universe) we see as a result gravity. When we look up at the sky, we see that all the galaxies have it “more ” stop—They seem to have more than we can comprehend. However, in a recent article, a A team of astronomers attempted to determine the effects of black matter on orbiting gas inside a distant galaxy, but they found that only natural phenomena could explain what gas is to walk. There was no room for black stuff, as they could see. The research team has been approved for publication in the Monthly Notes of the Royal Astronomical Society.

Filippo Fraternali, a astronomer at the University of Groningen in the Netherlands and co-author of the paper, told Gizmodo in an email that the astronomical group the group studied could be held together. only with its apparent quantity — which sounds quite reasonable, besides that black things believe that a the main thing in all galaxies. “The big problem is, In our case of galaxies, galaxies cannot produce without black matter; and more important, the galaxies need to have more mass, ”said Fraternali. “Then there’s something we don’t understand.”

The galaxy is called AGC 114905 and is about 250 million years old from Earth. It is very widespread, meaning that its story spreads over a large space; AGC 114905 is about the size of a Milky Way but they have about 1,000 time and few stars. The research team used the National Radio Astronomy Observatory’s Very Large Array Telescope telescope to observe the gas cycle in the galaxy for 40 hours, from July to October 2020.

The findings are similar to that on NGC1052-DF2, a different dwarf galaxy seemingly to lack dark matter that was  explained in 2018. Very quickly, a controversy it exploded at what he said; Some astronomers thought that the galaxy was a testament to the size of the new galaxy, while others thought that it was misinterpreted. and that the team needs more data. ThaThe galaxy of the ta’s can not just be empty was a very strange word.

Soon, the team double-checked the NGC1052-DF2 measurement, which seems to confirm the first group’s findings regarding the galaxy’s distance, and thus, its black material. Nicolas Martin, astronomer at the Max Planck Institute for Astronomy, told Gizmodo at the time that the galaxy “was probably created by chance and evolution” and “the good thing is that telescopes and future research will make it easier to understand NGC1052-DF2 and put obstacles in their place. In other words, is this system rare or partial? of older people who are not yet fully understood by the galaxies that make it? ” Now, wwith the discovery of AGC 114905, there is considerable evidence that human galaxies exist it cannot be explained by modern examples.

A recent team found that AGC 114905’s dark matter halo-feet of black matter in and around. galaxy – should be made of almost (if any) black matter to match what he collected. One explanation for this absence was that the galaxy was stripped of its black material by large galaxies nearby – except. there we areno no those galaxies around it.

“The concept predicts that there must be black matter in AGC 114905, but what we have seen is that it does not exist,” said Pavel Mancera Piña, an astronomer at the University of Groningen in the Netherlands and executive secretary of the paper, at the Royal Astronomical Society. Press release. “On the contrary, the distinction between doctrine and observation is widening.”

Another theory was that the part of the group that saw the galaxy made dark objects difficult to see, but author Tom Oosterloo, an astronomer at the Netherlands Institute for Radio Astronomy, also said that the side would be beautiful. exaggerated compared to team comparisons.

Now, the team is exploring the second most widespread galaxy, to see if they too are missing from the black department. If it does, it will encourage the team to study the first galaxy. Watching now in progress, and Fraternali said the group expects the same. The more we learn about it, the more intense the darkness becomes.
