Astronomers have tied the origin of a Fast Radio Burst to a highly magnetized, gas-filled region of space, providing a new hint in the decade-long quest to explain the mysterious radio pulses.
"We now know that the energy from this particular burst passed through a dense magnetized field shortly after it formed," says Kiyoshi Masui, an astronomer with the University of British Columbia in Canada and lead author of the new findings published Wednesday in Nature.
"This significantly narrows down the source's environment and type of event that triggered the burst -- and means the source of the pulse likely resides within a star-forming nebula or the remnant of a supernova."
