Identify the strongest, most distant radio signal source in the universe

FRB Origin Cluster 20220610A

The report, presented at the 243rd Meeting of the American Astronomical Society in New Orleans, Louisiana, shows that the most distant and oldest fast radio burst (FRB) ever detected came from a surprising location.

According to a report published on arXiv , astronomers led by a team of experts from Northwestern University (USA) have identified the source of FRB20220610A, the most intense FRB originating from the farthest place in the universe to date.

Discovered in 2022, FRB20220610A is believed to originate from a cluster of at least seven galaxies, thanks to images from NASA's Hubble Space Telescope.

The team suggests that the galaxies are interacting with each other and may be preparing for a merger. Such rare interactions between galaxies create the right conditions to trigger an FRB.

According to experts, the new study has raised questions about previous scientific models used to explain the FRB phenomenon.

"Without the Hubble image, the origin of FRB20220610A remains a mystery, whether it originated from a single galaxy, or from an interacting system," said study leader Alexa Gordon of Northwestern University.

FRBs are mysterious, ultrafast bursts of radio signals from deep in space. They flash and disappear in a matter of milliseconds, but release more energy than the sun does in a year.

FRB 20220610A is the most distant FRB ever recorded, but it emits four times more energy than FRBs at closer distances.

Scientists have detected up to 1,000 FRBs since the phenomenon was first recorded in 2007.
