Canberra, December 22, 2023 (Xinhua) – Australian astronomers have detected a seismic wave that formed in an ancient galaxy during the very early universe.
In a study published on Friday, a team from the Australian National University used the Atacama Observatory’s Large Millimeter Array Telescope (ALMA) in Chile to look at BRI 1335-0417, a distant galaxy more than 12 billion years old, in great detail. So as to get a better understanding of how they are formed.
The galaxy “BRI 1335-0417”, which was discovered by the ALMA Observatory for the first time in 2021, is the oldest and most distant spiral galaxy known in the history of the universe.
It is worth noting that a spiral galaxy is a galaxy that usually has a circular disk with spiral “arms” radiating from a central core.
Using the ALMA Observatory, researchers at the Australian National University were able to capture the movement of gas around the galaxy “BRI 1335-0417” and the process of seismic wave formation, for the first time in the world for a spiral galaxy from the early universe.
Takafumi Tsukui, the lead author of the research from the Faculty of Science at the Australian National University, indicated that the team seeks to discover how the galaxy “BRI 1335-0417” fuels the formation of its stars.
“We were specifically interested in how gas moves into and through the galaxy,” he said in a media release.
He explained, “Gas is a major component of star formation and can give us important clues regarding how the galaxy fuels its star formation process.”
They found that new gas is either flowing into the galaxy or touching young galaxies, providing fuel for star formation.
Given the vast distance between Earth and the galaxy BRI 1335-0417, the images seen through the telescope at the present time date back to a time when the universe was only 10 percent of its current age.
