Like gravitational waves (GWs) and gamma-ray bursts (GRBs), fast radio bursts (FRBs) are one of the most powerful and mysterious astronomical phenomena today.
, Pleunis and his colleagues relied on a new clustering algorithm that looks for multiple events co-located in the sky with similar DMs.'s sky position and dispersion measure up to a certain precision that depends on the design of the telescope that's being used," said Pleunis.that the CHIME telescope has detected and looks for clusters of FRBs that have consistent sky positions and dispersion measures within the measurement uncertainties.
With the help of this new algorithm, the CHIME/FRB collaboration detected 25 new repeating sources, almost doubling the number available for study. In addition, the team noted some very interesting features that could provide insight into their causes and characteristics. As Pleunis added: For many of the new sources we have detected only a few bursts, which makes the sources quite inactive. Almost as inactive as the sources that we have only seen once.
Any explanation for fast radio bursts should be able to explain why some sources are hyperactive while others are mostly quiet."
