They burned the candles of their lives at both ends and then “died” young. These are the six oldest and largest galaxies that astronomers describe today. They first formed a lot of stars in a short period of time. Then they ran out of fuel. And was forced to run empty.
Even today, ours (NASA) and Alma, Atacama Large Millimeter / Submillimeter Antenna Array, for objects from this period, Have made an astonishing discovery. Six large galaxies are said to be absent Necessary for the production of stars.Produces Daily. But when he was three billion years old – equivalent to 20% of his current age – he enjoyed the best time in history. However, by turning
“At that time we thought all the galaxies formed a lot of stars. And the largest ancient galaxies in the universe reduced the rate at which they formed stars a few billion years later. . But really, our work shows that these galaxies are not really slow. They really worked empty. “, University of Massachusetts (USA) astronomer Kate Whittaker said in a press release.
It is a combination of surveillance techniques that helped researchers make discoveries. With Along with the old alma, they were able to detect traces of cold hydrogen indicating where stars might form in the future. Finally thanks for an effect Production The front is very large and presents a Multiplied by all And a Unequal place, they were able to read the details of these six mysterious galaxies., They were able to find the stars in the galaxy
“Galaxies that do not form a lot of stars leave very quickly, and they are difficult for us to observe. The gravitational lens effect allows us to read them anyway.”, Notes Justin Spilker, a researcher at the University of Texas (USA). To understand that these six galaxies did not stop forming stars following their sudden inability to convert to hydrogen. But due to the shortage of cold gas tanks.
How? ‘Or’ What? The Supermassive and heated all the gas in these galaxies. Probably even because the cold gas supply to these galaxies was suddenly cut off. But anyway, these six galaxies could not refuel their tanks, so the star-forming machine could not restart.Still ignore it. Probably due Paid by
There is still a lot to learn …
“We still need to learn a lot about the reasons why huge galaxies formed at the beginning of the universe and why they stopped their star formation when they had so much cold gas., Describe Kate Whittaker. The fact that these giant beasts of the universe created 100 billion stars in just one billion years and then abruptly stopped their star formation is a mystery we all want to solve and here is the first clue for us.
