(Cnet) – Scientists suddenly have a whole lot more data on one of the strangest and most recent mysteries in the cosmos, so-called fast radio bursts (FRBs). First discovered in 2007, these fleeting blasts of radio waves originate thousands, millions or even billions of light-years from Earth. FRBs have influenced the design of new radio telescopes like the Canadian Hydrogen Intensity Mapping Experiment (CHIME). And now a team of Canadian and American researchers using CHIME has reported a major new set of FRB detections that could fine-tune our understanding of where these enigmatic signals come from and what produces them. The group says it’s discovered eight new FRBs that repeat.
“Repeating FRBs are highly valuable from an observational perspective since their repeating nature make them better candidates for localizing their host galaxies and multi-wavelength follow-up observations that can help determine if FRBs emit at wavelengths other than radio,” said Ryan McKinven, one of the researchers who is based at the University of Toronto and co-author of a paper about the FRBs. Those follow-up observations could provide details about the origins of the strange bursts, he added. A larger sample size of repeating FRBs to study could also help scientists answer one of the obvious questions about non-repeating FRBs: Could they actually be repeating FRBs that just haven’t been recorded as repeating yet?
