About a year after entering the orbit around the sun, the James web space telescope began to depict abundant red dots, which scientists, Um, said “Little Red Dots”. I know – not only the name is extremely unimaginable, it also gives a false impression of triviality. In fact, these little red dots are almost “broken” modern cosmicism.
Astronomers have collected one of the largest surveys of Little Red Dots (LRD) so far and a large part of these mysterious space objects with the supermasive black hole with the galaxy. Their results, presented during the 245th meeting of the American Astronomical Society in Maryland and accepted for the future Astrophysical journalCould solve “the universe-broken problem.”
“We are surprised by this new population that the web has been found. We do not see them in the analogs in Lower Redsift because we haven’t seen them before the web, “Dale Cosovsky, who led this study, who led this study, said at a Space Telescope Science Institute StatementThe
Redashift When the expansion of the universe extends light waves, their wavelength increases. This makes them more red because they “transfer” to the red part of the light spectrum. Partially because of the small red dots – you guessed it – red. Basically, the lower Redashifts match the distance near the space.
“Whether there is a lot of work to try to determine the nature of these little red dots and whether they are dominated by the acquisition of light [growing by accumulating matter] Black Holls, “added Cosovsky. Cosovsky and his team’s research was published in a September Preprint A.
In their survey almost all LRDs existed during the first 1.5 billion years of the universe. How do we know about the objects exist a few years ago? It takes time to travel to light because. When we observe the heavenly bodies, we don’t see them like today, but only when they started their light on the world. For example, it takes eight minutes and twenty seconds Tide On our planet This means we saw the sun eight minutes twenty seconds ago. The same is the case with the object far away. In fact, the farther they are, the more their redashift and the more “time back” we can see.
Don’t worry, there will be no quiz in the end.
Team study indicates that a large part of the LRDs existed in the question of 600 million to 1.5 billion years after the Big Bang in question. They also found evidence that many of them orbit the traveler’s gas around 2 million miles per hour (about 3.2 million kilometers per hour). Based on this evidence, researchers have suggested that LRDs can be active galactic nucleus (AGN): extremely illuminated and growing supermasive black holes.
“The most exciting thing to me is the distribution of Redashift. This is true that red, high-radiift formulas basically stops existing at a certain time after the Big Bang, “Steven Finalstein from Texas University of Austin said, who participated in the study.” If they are raising black holes, and we think at least among them Percent has only 5 percent, but it indicates in the era of vague black hole growth in the initial universe. “
When it first identified the LRDs, JWSti “will break” the cosmicness “right”. In this context, the possibilities of the stars of such lighting are widely accepted as opposed to the cosmic theories, suggesting some scholars that the cosmos was “broken”. The light emitted by AGN, however, adapts to those theories.
“This is how you solved the universe-broken problem,” said Anthony Taylor, a co-author of the upcoming research.
Although the Universe Breaking Problem may solve, many questions about LRD remain.
“There are always two or more possible ways to explain the misleading features of the little red dots,” Kosovsky said. “It finds the balance between the model and the observation that is well aligned between the two and the key conflict between the two.”
In the end, two of the studies from the study-do not judge any astronomy event by its name and even the problems of the universe can be fixed in the end.
