"The fact that the bursts are repeated rules out any cataclysmic models in which the source is destroyed while generating the burst", he added.
While most FRBs have been spotted at wavelengths of a few centimetres, the latest FRBs were detected at wavelengths of almost a metre, which opens up new lines of inquiry, according to the CHIME team. These could be created by rapidly spinning neutron stars that have been strongly magnetized or magnetars. The signals are so brief, they must come from something incredibly small (no bigger than the U.S. state of New Jersey) yet they pack as much energy into a millisecond as the sun emits all day. Ingrid stairs who is the member of CHIME Team have had an interview in which he said that till now there had been one repeated FRB and there are clearer confirmations that there would be more suggestions like there have been before out there.
Similarities indicate the possibility of the same emission mechanisms or propagation effects, they said. CHIME can only record signals between 400 MHz and 800 MHz. A lucky moment in 2015 resulted in the detection of multiple FRBs coming from the same location, which differs from random fast radio bursts that appear isolated in different locations.
"The environment of the FRB has a much larger effect on the shape of the signals at long wavelengths", said Good.
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. So far, scientists have very little information about where they actually might be coming from. What's more the lowest radio frequency recorded previously was 700 Mhz. CHIME was still in its test phase when it detected the radio waves and 12 other one-time bursts.
Before CHIME began to gather data in 2017 some scientists wondered if the range of frequencies it had been designed for would be too low to pick up FRBs.
"At the end of a year we may have found 1,000 more bursts".
"Or near the central black hole in a galaxy".
Over time, Stairs says researchers will hopefully be able to develop a "clearer picture" that could lead to figuring out what exactly is producing these radio waves. The $16-million investment for CHIME was provided by the Canada Foundation for Innovation and the governments of British Columbia, Ontario and Quebec, with additional funding from the Dunlap Institute, the Natural Sciences and Engineering Research Council and the Canadian Institute for Advanced Research.
"So what we've shown is that by discovering a second FRB is that the repeating FRB is not unique and maybe we can hope to find more", he said in the video interview.
