How the WebB Telecope’s ‘Small Red Points’

About a year after the orbit of the sun is launched, James Weba’s space telescope began to portray the abundance of small red spots that scientists called, hmm, “small red spots.” I know – not only is the name extremely unimaginable, but it also makes a false impression of insignificance. In fact, these small red spots have almost “broken” modern cosmology.

Astronomers have collected one of the largest studies of small red spots (LRDS) ever done, and theoretize that most of these mysterious cosmic objects are galaxies with over -fat black holes. Their results presented during the 245th meeting of the American Astronomical Society in Maryland and accepted for future publication in The astrophysical magazinecan solve “the problem of breaking the universe.”

“We are confused by this new population of sites we have found. We do not see analogs of them in a slower red shift, which is why we have not seen them before the Web, said Dale Kochevski of Colby College in Watervil statementS

Red shift It happens when the expansion of the universe extends light waves, increasing their wavelengths. This makes them look brighter because they “move” closer to the red part of the light spectrum. That is why the small red dots are – you knew this – red. In essence, the larger red shifts correspond to the closer distances in space.

“There is a significant amount of work to try to determine the nature of these small red spots and whether their light is dominated by accumulation (growth by accumulation of matter) black holes,” Kochevski added. Kocevski and his team’s studies have been published in September Pre -article of Arxiv.

Almost all LRDS in their study existed in the first 1.5 billion years of the universe. How to find out about items existing billions of years ago? This is because light takes time to travel. When we observe celestial bodies, we see them not as they are today, but as they were when their light first began their journey to Earth. For example, it takes eight minutes and twenty seconds for The sunlight to travel On our planet. This means we see the sun as it was eight minutes ago and twenty seconds. The same applies to objects, much further than us. In fact, the further they are, the higher their red displacement and the more “back in time” we can see.

Don’t worry, there will be no test at the end.

Team studies show that most of the LRDS in question exists between 600 million and 1.5 billion years after the Big Bang. They also found evidence that many of them had an orbit of gas traveling at about 2 million miles per hour (about 3.2 million kilometers per hour). Based on this evidence, researchers suggest that LRDs can be active galactic nuclei (AGN): extremely glowing and growing super -fat black holes.

“The most exciting for me is the distribution of red shift. These really red sources with high red shift mainly stop at some point after the Big Bang, “said Stephen Finkelstein of the University of Texas in Austin, who also participated in the study. “If they grow black holes and we believe that at least 70 percent of them are, it hints at the era of darkened growth of black holes in the early universe.”

It will also “correct” the cosmology that JWST “has broken” when it first identifies LRD. The possibility of stars to emit this type of light in this context is contrary to widely accepted cosmological theories, which causes some scientists to suggest that cosmology is “broken”. However, the light emitted by AGNS fits into these theories.

“Here’s how you solve the problem with the universe,” says Anthony Taylor of Texas University in Austin, co -author of the upcoming study.

While the problem of breaking the universe can be resolved, there are many questions about LRD.

“There are always two or more potential ways to explain the confusing properties of small red spots,” Kochevski said. “This is a continuous exchange between models and observations, finding a balance between what is well equated between the two and what conflicts.”

After all, the study is two: do not judge an astronomical phenomenon by its name and even the problems of breaking the universe can eventually be resolved.
