Astronomers detect a radio signal that traveled 8 billion years to reach Earth

by OnverZe

An eight billion year ancient energy burst has been found by an international team of scientists. This result demonstrates that the elusive matter between galaxies may be measured using fast radio bursts (FRBs), shattering the team’s previous record by 50%.

This ancient FRB’s origin was discovered to be a cluster of two or three merging galaxies, corroborating the prevailing beliefs regarding how these cosmic occurrences began. The scientists came at the further conclusion that FRBs can be located and detected with present telescopes going back about eight billion years.

The CSIRO’s ASKAP radio telescope discovered the FRB on June 10, 2022, and it was given the name FRB 20220610A. In just a few milliseconds, this cosmic explosion produced energy that would have taken our Sun’s whole 30-year lifetime to emit.
The source galaxy, which was found to be older and farther distant than any other FRB source detected thus far, was then found using the European Southern Observatory (ESO) Very Large Telescope (VLT) in Chile.

This finding supports the idea that FRBs can be used to “weigh” the universe, a proposal that was initially put up in 2020 by the late Australian astronomer Jean-Pierre “J-P” Macquart. Dr. Ryder claims that “our measurements confirm the Macquart relation holds out to beyond half the known Universe.”

The study reveals that FRBs are frequent occurrences in the universe, even if the origin of these enormous bursts of energy is still unclear. According to Associate Professor Shannon, they can be utilized to find matter between galaxies and gain a better understanding of the universe’s structure.

With the multinational SKA telescopes being built in South Africa and Western Australia, the future of FRB detection is bright. These will be considerably more useful for finding older and farther-off FRBs. The study of their source galaxies will then be required using ESO’s Extremely Large Telescope, which is now being built in Chile.

The current disagreement over the universe’s mass can be resolved in large part because to this discovery.

According to Associate Professor Shannon, “If we count up the amount of normal matter in the Universe – the atoms that we are all made of – we find that more than half of what should be there today is missing.” He continues, “FRBs can’see’ all the electrons, allowing us to measure the amount of matter between the galaxies.”

This might aid in finding the “missing” matter that is thought to be hidden in the void between galaxies.
