Slowly spinning the dark matter may explain the auras “small red points” mysterious in the early universe

Astronomers at the Center for Astronomical Physics Harvard & Smithsonian University has proposed a new explanation of some of the most confused early galaxies in the universe, nicknamed “Small Red Points”.

In the study, Posted in Astronomical physical magazine messagesThe authors, Fabio Bakchchi and Abraham (AVI), suggests that these galaxies are the result of a dark matter aura that rotates very slowly, which is a very rare cosmic structure.

These integrated, integrated things, which were discovered in deep space pictures of James Web telescope (JWST), challenges scientists to understand how galaxies and black holes in the early universe.

Their paper, “extremist cosmic values: a low -rush Halo explains abundance, pressure and the development of red displacement of small red points”, provides a material explanation of the distinctive characteristics of the points.

“The small red points are very compressed and red, far from the galaxies that were not completely discovered before the James Web telescope,” said Bakucci. “It can be said that it is the most surprising discovery by JWST so far. Our work shows that this can be naturally formed in dark matter auras with a very low spinning.”

A puzzle in the early universe

Bakucci said these galaxies are primarily visible when the universe was only one billion years old, but it may have been much earlier. Although it is about the tenth of the size of the typical galaxies, astronomical notes show that they appear unusually bright. Astronomers believe that their amazing red color indicates that they are in dust or filled with ancient stars.

For years, astronomers discuss whether the light we notice from these things is created by stars or super high black holes.

“It is a basic mystery,” Bakucci said. “If they contain black holes, then these black holes are enormous for such small galaxies. But if they only have stars, the galaxies are very compressed so that they cannot all contain them, as they reach wonderful central densities that cannot be imagined.”

Instead of focusing on what enhances the bright points, PaccCCI and LOEB followed a different approach: they have studied how these beings can be formed in the first place.

Low -rotation cycle

Dark material auras are the invisible scourges around which galaxies are formed. In their paper, the authors show that the luminous points are formed in the auras that are at the lowest 1 % of the rotation distribution. In other words, 99 % of all auras rotate faster than those. These low low auras will naturally create very pressing galaxies. Just as it is very similar to riding fluctuations in the carnival, the faster the aura, the more expanded than the fluctuations, causing a galaxy to expand its center; Likewise, the slow rotation keeps the radius of fluctuations smaller.

This hypothesis also explains the reason for the relatively rare points: it represents only 1 % of the abundance of typical galaxies, but it is more common than parallel, super -high -center black holes that sparkle in the midst of some galaxies.

In addition, it helps to clarify the reason for observing the bright points only within a short period of one billion years in the early universe. With the development of the universe, the dark material auras grow larger and gain more angular momentum, making it difficult to create low -rotating compressed galaxies.

“The dark material auras are characterized by the speed of rotation: some of them spin very slowly, while others are going on more quickly,” said Lub. “We have shown that if you assume that the small red points are usually in the first percentage of the distribution of dark circles, you explain all their monitoring properties.”

The main environments of black holes

Although the paper does not solve whether the small red points are supported by stars or black holes, they indicate that they are major environments for rapid or black stars.

“Low -convictions tend to focus the mass in the middle, which makes it easy for the black hole to increase the material or the stars are formed quickly,” said Bakucci.

Some points show wide emission lines in their spectra, which are possible signs of active black holes, but they lack the usually associated X -ray emissions. Paccci leads new programs to better understand the nature of these astronomical physical sources. For example, finding similar galaxies will be found furtherly evolving in space.

“We did a step towards understanding these mysterious things,” he said. “They may help us understand how the first black holes formed and develop with galaxies in the early universe.”
