Astronomers find clues in Fast Radio Burst Mystery
Fast Radio Bursts (FRBs) have baffled scientists since they were first detected about 10 years ago. A new study has found first real clue on origin story on the energetic, seemingly random bursts. Nature published study has suggested that the mysterious pulses most likely come from an area of dead or newborn stars.
Since the discovery of the pulses in 2007, only 16 FRBs have been recorded, but astronomers think they may occur many times every day. Origin of the pulses was a big question for astronomers since the first recorded pulse. According to the new study, region dense with either the birth or death of stars could be the origin spot.
Jeffrey Peterson, a researcher from Carnegie Mellon's McWilliams Center for Cosmology and an author of the study, said in statement, “Hidden within an incredibly massive dataset, we found a very peculiar signal, one that matched all the known characterizes of a Fast Radio Burst, but with a tantalizing extra polarization element that we simply have never seen before”.
Astronomers studied the polarization of the pulse and found that the burst passed through a strong magnetic field. They also determined that the pulse also passed through two ionized gas after magnetic field. The first wave suggested that the burst came from a nebula surrounded area or its own galaxy’s center.
Lead author Kiyoshi Masui, an astronomer from the University of British Columbia in Canada, said the study has proved that the pulse passed through a strong magnetic field shortly after its formation. It has narrowed down the possibilities of origin of the FRB.
