"The fact that the bursts are repeated rules out any cataclysmic models in which the source is destroyed while generating the burst", Tendulkar added.
In 2017, Professor Avid Loeb, from the Harvard-Smithsonian Centre for Astrophysics in the United States, proposed that FRBs could be leakage from planet-sized alien transmitters.
This sudden influx of tantalising clues has made astrophysicists nearly giddy.
This work was published today (Jan 9) in a set of papers in Nature.
Scientists believe there could be up to a thousand FRBs in the sky every day.
The remaining steps in the CHIME pipeline are L3 (flux estimation, source identification, extragalactic check, and an action decision); and L4 (action implementation, database operations to store header data, intensity data, and baseband data; offline analysis and a Web interface with alerts).
Yet, two elusive signals have been found that burst into life again and again - and for these, there must be a different explanation.
Collaboration have spotted 13 new fast radio bursts (FRB) - powerful radio flashes probably arriving from far outside the Milky Way, with mysterious origins that continue to be a matter of debate. "But I think we're reaching the peak of that mountain".
Man held over suspicious packages to Pak, other embassies in Australia
A man has been arrested after almost 40 suspicious packages were discovered at foreign embassies and consulates across Australia . Avan, who was originally said by police to be 48 years old, will next appear in court in March.
Even though FRBs were detected in 2007, it was only in 2015 that the Arecibo radio telescope in Puerto Rico detected such repeating radio waves.
The flashes last only for a millisecond but they are ejected with the same level of energy the sun takes 12 months to produce. The new observations suggest FRBs are common at lower frequencies.
There are a number of theories about what's causing FRBs, including the possibility that a neutron star is releasing powerful signals after it exploded or even, albeit held by only a small minority, that they're signals from an alien civilization. Among the FRBs, was the second ever repeating fast radio burst recorded. "Knowing that there is another suggests that there could be more out there", Ingrid Stairs, a member of the CHIME team and an astrophysicist at UBC, said. Seeing a signal at all indicates something big, like a black hole collision, could be the cause.
"Until now, there was only one known repeating FRB".
Astronomers' studying of FRBs can teach those who study more about where the bursts come from, and whether that region in its galaxy is home to turbulent gas.
There have been more than 60 FRBs observed by researchers to date; however, scientists have only ever recorded one other repeating burst from a single source. "The luminosity difference is many, many orders of magnitude", she said.
Kaspi said CHIME quickly detected a source that sent out a series of six fast radio bursts.
Mysterious signals have been picked up from distant galaxies. The signals travel billions of light-years through the cosmos but only last a fraction of a second, making them hard to study.
