Fast radio bursts are intense, short-lived blasts of radio waves hailing from beyond the Milky Way that can emit the same amount of energy in just thousandths of a second that the sun takes three days to emit.could erupt in the sky over Earth every day, these blasts of radiowaves remain mysterious. One of the biggest puzzles surrounding FRBs is why most flash once and then disappear while a tiny minority repeat the flash.
"Other studies have looked at the polarization of maybe 10 non-repeating FRBs, but this is the first time where we've looked at more than 100. It allows us to reconsider what we think FRBs are and see how repeating and non-repeating FRBs may be different."In 2007, astronomers Duncan Lorimer and David Narkevic, who was Lorimer's student at the time, discovered the first FRB. It was a non-repeating burst of energy that's now commonly referred to as the".
"If the polarized light passes through electrons and magnetic fields, the angle at which it's polarized rotates, and we can measure that rotation," Pandhi said"So if an FRB passes through more material, it'll rotate more. If it passes through less, it'll rotate less." One of the big surprises this research delivered for Pandhi was that the polarization of non-repeating FRBs seems to clear one of the major suspects behind their launch: highly magnetized, rapidly spinning
