Using advanced statistical tools and CHIME, the research suggests that all FRBs may eventually repeat, with differing burst durations and frequency ranges, indicating different origins.
Now, a large team of astronomers, including several from the MIT Kavli Institute for Astrophysics and Space Research and the MIT Department of Physics, have collaborated on work to decipher the origin and nature of FRBs. Their recent open-access publication inreports the discovery of 25 new repeating FRB sources, doubling the known number of these phenomena known to scientists to 50.
The team also concluded that all FRBs may eventually repeat. They found that radio waves seen to have burst only once differed from those that were seen to have burst multiple times both in terms of duration of bursts and range of frequencies emitted, which solidifies the idea that these radio bursts have indeed different origins.
