A study reveals a link between repeating and non-repeating fast radio bursts (FRBs) through their energy distributions. Using four 25–32 m class radio telescopes, researchers observed the hyperactive repeating FRB 20201124A for over 2,281 hours, detecting 46 high-energy bursts. These results suggest that apparently non-repeating FRB sources may simply be the rarest bursts from repeating sources. The energy distribution of repeating FRBs resembles that of non-repeating FRBs, indicating a possible common origin. The study also shows that FRB 20201124A contributes significantly to the all-sky FRB rate and that similar sources would be observable even at very high redshifts. The burst energy distribution of FRB 20201124A is found to be flatter than previously observed, suggesting a difference in emission mechanisms between low- and high-energy bursts. The study concludes that FRB 20201124A may be a link between repeaters and non-repeaters, with its high-energy bursts resembling those of non-repeating FRBs. The results highlight the importance of studying FRB energy distributions to understand their origins and potential applications in cosmology.A study reveals a link between repeating and non-repeating fast radio bursts (FRBs) through their energy distributions.
