Astronomers discovered a distant galaxy a “cosmic fossil” remaining “frozen in time” for billions.
As Fossils in Dinosaur On earth is used to check the evolution of life, this cosmic fossil in the form of children’s galaxy j0842 + 0059 can be used to understand cosmic evolution.
art Cosmic Fossil A galaxy that has committed remaining unchanging collisions and interactions with other galaxies. That means they can act as timen time capsules to help the astronomers study the early galaxies.
The new research held using data from the large telescope telescope (LBT) reveals that this Galaxy remains unchanged in about 7 billion years.
“We have discovered a galaxy ‘fully stored’ for billions of years, how is the development of the universe so far,” National Institute of the Crusensics
“Fossils are like dinosaurs in the universe: They are studied let us understand how the environmental conditions they have seen and how many galaxies they have seen are now changed.”
Kids are good
The children of J0842 + 0059, located 3 billion lights from the ground, discovered in 2018 in children (kilogram degree surveys).
Images of galaxy given to Maximum telescope telescope (VST) allows astronomers to measure the size and masses of J0842 + 0059 children. These measurements are perfected by Very large telescope (VLT) and the X-shooter instrument.
It reveals that J0842 + 0059 children have a stellar mass for about one hundred billion times in the sun, but more compact than the same galaxies in the masses. Also discovered that J0842 + 0059 children are missing Star formation for most of its life. All it shows this one fossil galaxy.
To get uncertainty around the attitudes of children J0842 + 0059, especially the size and structure of it, this team uses more images of this relic galaxy. This results in images with ten times the details of children giving images.
“Data from LBT allows us to confirm that the J0842 + 0059 children are actually compact and therefore a true relic galaxy that is similar to NGC 1277 and compacted galaxies we saw in the first stages of the universe, “The Member Member Member Chiara Spiniello, a researcher at the University of Oxford, said it in a galaxy rela so far away. “
NGC 1277 another instance of a remarkable haltic fossil, located in Continue Cluster About 240 million light-theealles away, which means it is closer to home than the children of J0842 + 0059.
The fact that there are galaxies such as NGC 1277 and J0842 + 0059 kids showing that some galaxies can form, to keep compacting and stay dodging DISPUTES to other galaxies.
“Studying these cosmic fossils help us reconstruct the formation of the nuclei of today’s massive galaxies, which – unlike relic galaxies – have undergone fusion processes, accreting matter right around those first compact galaxies from which they are originated,” tortora said. “In cutting technologies like pressing options and the support of telescopes such as LBT, we can improve our understanding of this type of galaxy.
“In the near future, we will first find, seek to find, confirm, and study new galaxies that are relikes quality quality and high resolution Euclid Space Telescoffocko. “
